Whats the difference between these two motors?

So I'm looking to purchase a new racing motor for my E-buggy and I'm set on one from Hobbywing, as I have a Hobbywing ESC and I want to use the full-sensored mode that the ESC offers.
Up untill now I have used an 'ok' off-brand 2000kv motor with fairly weak batteries.
I'm looking at either the Hobbywing 1900kv motor or 2200kv motor. I know most of you are thinking "1900kv is king" right now, but hear me out.
I don't race on your typical tracks, especially the ones you see in the US. I race on everything from tight dirt tracks to crazy grip astro tracks to a HUGE multi surface track with a 100m straight.

Now to the actual question: What would be the better option: Buying the 1900kv and changing the gearing for the different tracks OR buying the 2200kv and changing the gearing + turning the power down/up on the radio.

I know 2200kv is overkill but I have a feeling 1900kv might be 'underkill'. It would seem that the 2200kv would give me a little more versatility, but Maybe I'm seeing this wrong. Anyway I'd like to hear your thoughts.

My opinion- I’d still go with the 1900kv. It sounds like most of the mixed surfaces are higher grip. That means more amp draw so harder to manage temps and run time. A 1900 kv motor will move a 1/8 scale buggy as fast as it’ll ever need to go and should give you at least as good an operating range.

FWIW, when I ran 1/8e on medium sized tracks, I used a 1700kv. While the 1900kv was slightly faster than me at the end of a straight, I had more punch than the traction could harness (set my speed control's current limiter to 65-70%), was able to make a 15 minute main on 4,500mah/4s packs.

temperature management,
battery management.

gearing, amp draw, motor heat... then there is RUN TIME..
a dialed back motor is not as efficient as a properly selected motor for the track and gearing.

Whatever track you're going to go to most go and see what everyone else is running and pick the closest thing to that.

As Davidka stated, you will be best served at 1900KV, a few years ago everyone was trying to run 2000-2200 KV, yet these days with changing track conditions, smaller tracks, a 1900KV is a safe bet. You wont be overpowering your buggy when grip is strong, and the same you wont be wasting power when there is a lack of grip.
