I haven't played on a 25" for a long time, so I can't say what's better, but I love my 29" (or 27", depending on where in the world you are) Candy cabinets to death. Even my old games, like Rygar looks great on it. NANAO MS9 for the win.
Also, when selecting the resolution to run on that 32", do yourself a favor and pick the one that gives you the best geometry rather than higher resolution. I had a 31kHz screen in my old Wei Ya cabinet and unless I ran it in 480p I had terrible geometry issues. No 15kHz joy for me, so I sold it.
