MAME4droid (short for MAME for Android) is an Android port version of the most popular arcade emulator MAME (only version 0.139u1) that was developed by Nicola Salmoria and the MAME team, made by David Valdeita (Seleuco). It is able to emulate all romsets supported by the original MAME of this version.

M+GUI (AKA: MAME Plus! GUI) is another new quality GUI front-end for MAME, developed by a fan player from China. We can see it as a fast Qt implementation of MameUI (that means they have similar functionality and user interface).

The official MAME is an application based on all platforms, for Windows it only runs in a classic DOS/CMD window. So this has given rise to many GUI front-end tools and derived editions based on MAME. Although MAME is still the best multi-console arcade machine emulator with the most exuberant vitality in the history of video game machine emulators, what made it is just those many variant editions.

First you should know one thing - MAME32 Plus! Plus! is equivalent to a secondary-strengthened edition of MAME32. It has super fast emulation speed and pretty good compatibility that any emulator under the same series (GUI edition of MAME) can't catch up with. The most obvious one point is you will find its game check/audit speed is several times of (or even dozens) MAMEUI32 or MAME32 Plus!.
