Yes...1/8th is faster (apple to apple compare to 1/10th)
Yes...1/8th can handle better then 1/10th (if your setup is right) and could be yes that 1/10th is easier to drive then 1/8th due to less power...less power, easier to control

But before heading to 1/8th, make sure you have a track is big enough for 1/8th.....1/8th is not that fun when it is running on a 1/10th sedan tight track.

Also, I would say...1/8th is 2X the price of 1/10th......unless you have it used, like me........

the 1/8th cars should be faster in the same hands. More power etc. But to my experience driving the 8th feels easier than touring cars due to their lola bodies and the width of the cars. They feel more stable and less twtichy than 1/10th. The hard part seems to be getting the absolute best out of the 1/8th car.
This is from a beginers point of view though. And i started with the 8th before i bought the 10th.

cheers

Was that an HPI Proceed or HPI SuperNitro you used to own ?
HPI SuperNitro is just a "super-sized" 1/10th scale sedan. And it is not any faster than any 1/10 200mm cars. Unless you slap .21 on, but then it'd be overpowered and harder to drive.

I would say that the 1/8 are a little more twitchy then the sedans.

1/10 tc is easier to drive. The differentials & lower power levels, lower speed, make it so.
Set-up is very different for 1/8. 1/8 is deffinately faster. 1/8 is more expensive.

My 8th outlasted my nitro sedan in durability. They do hit harder though, but for the minimal taps you barely break anything. Sedan really isn't much more expensive than 8th as people say. The only difference is the price for engine. You can get an inexpensive engine for a medium size track costing you only $300-$350, the Vega Scud .21 circuit especially is one of the most powerful inexpensive you can get. Otherwise on a huge track pay a bit more, or still go with that Vega Scud. On both cars though setup matters extensively. Without it, both cars will handle like crap especially with a powerful engine. Do the best thing and invest in a setup system for your cars. If you want to really make 8th the most inexpensive, check out the PRP XR8. You can get the car, engine, and pipe for about $600-$700.

Default Size Matters...

Track size matters when it comes to coming the two classes also. If your local track is small to med, you will definitely see close times between 1/10 and 1/8. On large tracks where a 1/8 can open up then you see the true power and speed. Matter of fact the last few races I attended were on med-lrg tracks and the TQ (Top Qualifier) for the both classes were the same number of laps. The one good thing about this sport is SKILL does matter. Having the most expensive equipment means nothing if you cant use it.

Will driving an 1/8 scale make you a better 1/10 scale driver??

My experience for on-road:
(I have an MTX-4 and 960)

1/8th
- A lot faster
- More stable
- A lot more durable
- Higher costs (fuel, tires, bodie, kit price)
- Power plant (engine + manifold + muffler) is more expensive

1/8th on-road are a lot of fun due to their high speed and represent the F1 of on-road RC. They also tend to take crashes a bit better. Their wide tires supply quite a lot of grip and stability. On the other hand, due to the high torque their engines output, wheels slip is a common problem when driving.

1/8th requires a LOT of maintenance and you will spend much more time on them than 1/10th. They have more parts and need to be set up properly. They are very sensitive to poor setup or incorrectly assembled parts. The high momentum generated by the car's high speed magnifies even the smallest of problems into big ones.

1/8th engines tend to be more stable than 1/10th but are more sensitive to changes in air temp and clutch settings. You will see 1/8th drivers constantly adjust their engines on race day. Clutch setting is also very critical. If you don't know what you are doing, blowing up your 1/8th engine is easy and not an uncommon site on raceday.

1/10th
- Lower kit costs
- Less durable
- Lower usage fees (tires, bodies, and fuel)
- Easier assembly
- Easier to drive due to lower speed
- Lower powerplant costs

1/10th cars are recommended as a starting point for on-road RC mainly due to costs but also due to their slightly more simple construction compared to 1/8th. Being 'slower' they are easier to drive but surprisingly, their overall lap times aren't largely different with 1/8th.

The smaller tires of 1/10th can lead to grip issues but the car's lower weight helps and you have a lot more options regarding differentials to overcome grip issues. There really aren't any options for on-road 1/8th on diffs.

1/10th engines tend to be less sensitive to changes in air temps but also tend to be more fussy about needle settings. If you lean out your 1/8th too much the engines bogs noticably but with 1/10th it tends to meltdown. You must take more care with your needle settings. Mistakes with your clutch may diminish your lap times a little bit but generally don't kill your engine.

You'll need to check the front bearing and conrod on your 1/10th a bit more often as they tend to need changing more often than a 1/8th.

As for driving, sure 1/12th sounds like a great way to practise.
