Play them all. Your friend has an awesome collection. Keep playing them all and you could change your mind on what you like. My wife loves.. loves loves our GBLE. We have had it for a year and she still plays it nearly every day. I love TWDLE. If you buy one and after a while still do not like it.. Sell it and go again. Sparky (Metallica) says when he likes things.. Again! Going forward we are putting playfield protectors on every machine. We love them.
I would not be too concerned about all the "supposed issues" with Stern quality. Ask your friend if he has any "quality issues" with his machines. Stern and our distro have always resolved any issues we have had.
Happy Flipping!
