No standard answer for that.......
you have to come up with your demands and situation, define what you want, search the market and make your choice.
All the recommendations given might not work for you at all!
Your choice depends on:
-your weight. Some are limited.
-your mission. Will u Use it every time you fly, just for phase 1 or just when doing aerobatics?
-your wallet. Used ones are cheaper. Import taxes from the U.S.
-your leg length (backpack normal/slim or seatpack)
-your upper body height when sitting. (Seatpack or backpack)
-your seat cushions (removable??)
-packing intervals (if you care)
-access to packing facility
-width, height and length of the packed chute
