More servo the better

I use an airtronics 94360 for steering. I think its like 110 or so in. lbs. and .07 transit. My throttle is a futaba 3010. Not a big crazy servo there, but does quite well, and has enough torque to stop my car dead in its tracks, and quick enough to transition from brake to full throttle well. I like the quick steering however...makes it more like a 1/10 electric buggy (my first RC car was a gold tub rc10 
)

You are certainly entitled to your opinion, however, I DO notice a few hundreths of a second. Maybe someday you will also. And, on a high bite track the additional torque, along with a truggy servo spring, prevents the front tires from pulling to center when exiting a turn under full throttle. Again, you might not notice it but many of us do.

I ran a slightly older Airtronics 94757, ~115 @ .07. It was good, and plenty fast, but it was a little on the weak side. Coming out of corners on higher bite tracks I could feel a little torque steer.

I've been running a Hitec 5945 on my steering for 2 years and have been extremely happy with it. For throttle I have always used a Air 258 (earlier version of the 358). I noticed a bigger difference by going to a fast strong servo on throttle than on steering. Anything faster than .15/60* is good for steering in my opinion (maybe I'm spoiled because my currnet steering servo is pretty fast) but the faster the throttle/brake servo the better. You'll really notice the reduced lag from throttle to brakes.

I use the Ace DS1015 with 201 oz./in torque and .10 speed in my Losi 8 buggy. Yes, with 6.5v li-po it's a bit faster. And, yes, I can tell the difference of .02 seconds but I'm certainly no god. And I'm certainly not the only one. I'm looking for a faster Radio/RX system also for the same reason.

i run a jr ds8715 (12kg of torque and .09 speed) for steering in my buggy
and a ds8455 (6.5 kg of torque and .1 speed) for my throttle
they do the job well and havnt had a problem with them yet
in my truggy a got a jr z9000t (320 oz of torque and .15 speed) for the steering
and the throttle is a jr z9000s (128 oz of torque and .06 speed)
they should do the job well but i havnt driven the truggy with em in it yet

Don't alot of team drivers still run analog? I know drake ran the airtronics servo mentioned for a long time.

If you want to race a lot you are pretty much stuck with a $100 servo for steering. I like the Hitec 5955 with 333 oz at .15s. It is faster than the Airtronics 358/359 that claims .10s. I have been using Futaba s9350 on throttle and occasionally steering on buggy. However I have found as my 9350 servos age they lose torque on steering so I have been switching vehicles to the Hitec.
I did use a Futaba s9351 for truggy steering last year but the main gear only lasted 1 year and now with new gears the motor is getting pretty tired. I also blew a new one up in two races which was a disappointment. No I did not set the endpoints wrong, and I have 3 9350 servos that are 2-3 years old with no failures so I do know what I am doing.
I used to think 140 oz was enough for a buggy. Now that I run with 300oz I know 140 was not enough to make the steering as consistent as possible.
You can get by with 120-140oz on throttle brake and probably less if you do not need super brakes. Typically these servos cost about the same as the 300 oz ones though.
If you are not racing and just want cheap the Jr 650 is pretty inexpensive and probably has enough torque to get you by.

I was sponsored by Hitec and after 2 years of failures and lost races I parted ways with them. I run airtronics now, and didnt pay attention to the diffrence in digital vs. analog. I was mainly concerned with reliable servos that didnt have !!! bogus claims !!! on speed and torque. Im trying to decide if I am missing something with the analog. What does tebo run?

The Associated RC8 had a DS1313 on th/br and a DS1015 on steering at the iHobby show. I'm guessing anyone sponsored by AE runs them. They are made by Thunder Tiger and branded with Ace Digital and now Associated.

run a couple of Hitec 5955's and be done with it. overkill, but you never have to worry about them.
