Death Smiles is good, I can't speak for Progear ( I haven't tried it yet ) but it looks good. But I'm with Kernow, all the "BEST" Cave shooters are vertical like both Espgaluda's, Dodonpachi series, Esprade, Ibara, etc.
The DS games are great to have at home in a cab. Being able to choose the path and difficulty of each stage is nice. It's even better on MBL with the option of 999 rank and the extra stage.
