Can of worms discussion 1/10th 4WD

[Kelk]

OK so I know thisn is going to be a right little can of worms but I have a "What are the pros and cons of which car?" for 1/10th $WD

I feel like getting a 4WD and the current naieve short list is:

Schumacher CAT K1
Kyosho Lazer
Assocaited B44.2 (of some iteration)
X-ray something or other

I race a TLR 22 and 22SCT at SHRCCC on astro and on the odd occasion go to TORCH / A. N. Other track/s

I'm looking for the pros and cons of each - build, quality, reliability, robustness, availability of parts, upgrades , potentiasl end of production run for a new car , absolutely anything

I used to race a Pro-cat many moons ago so there is a hankering towards the K1 but that is purely nostalgia talking

Thanks
