I run both tak and cat machines. I have a few tl150s, a few 287Cs and a few 289C models.
287 least damage to ground when operating. least amount of pushing power.
289 does a decent amount of damage to ground but with the suspension its not as bad as you'd think. pretty good pushing and digging power.
tl150 does alot of damge to the ground but will push and dig like no other skid-steer. very rough ride, but huge cab and never any problems.
the cats are very small inside. extremely uncomfortable if you're a bigger guy, which i'm not but I can imagine it would suck to be in a cat.
I've demoed most brands mentioned above. The tak and cat get my vote. Cat is our machine of choice for loaders, excavaters, hoes etc.
If you don't own anything machines other than a skid-steer, i highly recommend you get a tak because it will allow you to do bigger jobs that arent meant for small machines. you'll never say "I should've gotten a bigger machine"
I dug a foundation using the tak and a 287 a few weeks ago. you can do alot with these little machines
