I have no experience with ethier of the machines you pointed out. I have owned many manual and cnc machines, small to large, and will say, buy a machine that you will be able to use down the road so to speak.
It seems that we buy a machine, you say months later, man I should have got something bigger. The purchase all depends on how much money you can spend. But for example, for 10k, you buy a new small machine, most likely with steppers motors, or buy a older vmc, or knee mill conversion, with servos. Look at the big picture down the road. IF I knew what I know now 20years ago, I could have saved myself alot of time and money for sure.
Good luck on your machine purchase.
