MALA is still my FE choice for sure. I can go on and on about why that is but I'd be preaching to the choir with this crowd. Mainly, I like collecting extra media and reading the history file along with all of the artwork that you can define in mala very easily.
I have to say however, that for the games that HS has themes for already, it's pretty attractive. for ppl that come to your house and don't care to examine the PCB pics or arcade flyers, or your long list of games.
