MameUI or IV/Play

Hi lads,

The GF is eager for me to dust off my 2 player X-Arcade stick so I'm getting MAME setup after a few years of an absence.

The last time I used it I was using MAME32. I see this has been superseded by MAMEUI and that there is also a frontend on top of that called IV/Play.

Which is the better one?

I'll be hooking a laptop to the TV using HDMI and plugging he X-Arcade into the laptop.

Thanks.
