100%'d them in English at least once a year since forever >_> (for those "ach-tually" nerds, yes that means 101% in 1, 102% in 2, and 103% or 105% in 3 depending on my mood)

Fun differences I noticed:

DKC1 has a way more vibrant and colorful title screen
You can kill the rock-krocs with a handslap while they're curled up lol
Manky Kong takes 2 jumps from Diddy to kill
The world map actually has the ! at the end of the world names to signify that you found every secret in that world (US DKC1 doesnt have this)
Apparently the game is overall easier with different enemy placements and more DK barrels, but I didnt really notice >_>

The only thing I noticed in DKC2 is that it only costs 1 banana coin to save instead of 2

DKC3 doesnt have much either. There's more bees in the Lost World level where you gotta scale the cliff by jumping on the upward shooting barrels
And when you beat K Rool in Lost World, it auto moved you to Wrinkly's Cave so that she'll tell you about the banana birds. In the US, it just unceremoniously dumps you on the map and you gotta figure out to go to Wrinkly's yourself >_>
They also fixed the missing G in the Rocket Ship level

Overall the Japanese versions came out later and are easier (except 3 which is technically harder in 1 level I guess). It was kinda interesting see and mix it up a bit, but I probably wont do this again >_>

AMA?
