Differences are mainly this, in 1.01:
-Better quality servers
-More blocks
-No backwards roll (unless you jump first)

That's it really, if you stay in the Base JKA community. If you go to JA+, they differ. Yes, some remove the effects of poking, but eh. 

Are you from the US, or EU? 
If you're really interested, the DGAF server is a common US base pug server. If you're looking for base ffa/dueling, you'll mostly look toward Shadow Order.

In the EU, there's Lollipop for tffa and Thund's for duels. Not many ffa servers. I suppose the phantom academy EU is probably the only ffa EU I know of thats base and even that isn't entirely base. But it's not JA+ lol.

If you want JA+ that's decent, there's always JAWA I suppose. But that's all personal opinion/generalization.

Overall though, I think you'd like 1.01. It's not nearly as bad as the old stories claimed from diehard 1.00 players

@The question of switching, there's patch commander but I've never tried it personally. I would just make a copy of your files, put them in a "1.00" labeled folder, patch over the game files and switch back and forth as-needed. That's what I do, anyway.

If you wanna stay in contact with the whole of the JKA community, you may consider joining the JK Community Discord where pretty much everyone goes.

1.00 players are out there-- myself included. But after the clan I led died, most of us went 1.01, so all thats left is the hungarian community and a few guys from the spanish SAO clan to my knowledge (our clan was kind of the entire EU/US community there, lol).

Trunks seems familiar, I feel like Artemis has mentioned you before but I might just be thinking of someone else. 

I know some Clerics and AX players. But again, most that I know are either on break or moved to 1.01 because of the low activity on 1.00.

Was initially against it (Discord as a whole, I mean), but I've been checking it regularly now.

The JKC Discord is an absolutely amazing way of being able to contact basically anyone in the JKA community or leave them a message-- something that I had serious trouble doing after xfire died (I hate steam with all the fury of an angry mynock). 

Gets my endorsement. Trying to get more people to use it so that everyone can kinda be in one place.

Never got to see the difference, was never around during its best, but when I was first starting, nearing on two years ago now that I think about it, I loved all the in-depth reviews about the maps and such.  Was the highlight of using JK3files for me. Aside from being accurate, some also had a mild sense of humor that you don't really get from more cut-and-dry reviews you often get with games. You know, the ones that sound more like you're reading a documentary written by a monotone robot than finding info on a videogame. Gave a sense of personality that honestly made me want to read the reviews through even if I had no intentions on actually downloading the map.

That all said.. Always did bother me that it seemed almost anyone who wasn't from the USA couldn't access the website. Never really understood what caused them to be blocked that way.

Soo I'm Wolfeye, but you can call me wolf.
...I'm a liiiitttle late getting here.

For those who don't know me, I'm a clan leader/founder from the JKA 1.00 community who occasionally travels to 1.01 (Usually for things involving A-Mountain on the ups server or bothering the DE guys). I only found jedi academy about a year and a half ago, so I'm relatively new but more than happy to help the community in any way I can.
For those who do know me... Well, I only can think of one person besides Circa who will know me here soo.. Hi Art! (feel free to chime in if you do, I honestly don't know how many other people have beaten me to getting here).

Guess it was about time I joined into the awesome JKHub community so, here I am!

I'm not exactly the best with introductions or first posts sooo.. suppose I'll just leave it at that and say I'm glad to be here and it'll be nice meeting all of you
