I absolutely love love love my XT Racing GPX Pro (the first generation version). It's worked flawlessly for many years on many bikes. However, the newer versions have a couple of fatal oversights IMHO. The external antenna is a ball ache, and seems completely unnecessary as the early version with the integrated antenna misses about one lap every year or so, which is a very worthwhile tradeoff. Secondly and most importantly (by a million miles and a complete deal-breaker for me) is that the new ones don't turn on automatically when you switch the ignition on! The old one is really really really 'set and forget', as you can mount it out of the way and never have to touch it except to download data occasionally. Having to power on the new one each session is annoying in the extreme (and the buttons are definitely NOT glove-friendly).
Before I pancaked my Starlane, I quite liked it. Oh, it was fiddly to use, the buttons never worked properly, and the software was.... well.... Italian. But it had bluetooth (this is 10 years ago when almost nothing had bluetooth), which meant downloading data without going near the bike, let alone having to frig around with cables etc. Best. Feature. Ever. I don't understand why the others all STILL don't have this.
For my money, I'd get the Aim, mostly because everyone else has them, and sharing data is easiest.
