IMO
The shipped Sprint 6.1 rom is very stable and fast if it is configured properly. You just have to invest some time to trim some of the fat and set it up the way you want it. If you want eye candy then it's probably not for you. The 6.5 Sprint rom however, has some problems that I would rather not deal with.
Flashing a custom rom is the fastest way for you to reconfigure your device. A chef configures and tweaks (cooks) it the way they like it and/or the way thier users want it and then you flash it to your device. With custom roms you usually get to use the newer versions of Windows Mobile and in some cases experience better performance and more capability than you would with a shipped rom. Although, depending on what the rom chef includes or takes out of the rom some things may not work as well as they do with a shipped rom. This is why what one person likes may not be what another person wants. You probably will have to try a few to see what you like. There are many to choose from.
If you want a really personalized rom you can use a kitchen and cook your own rom. If you decide to do this there are probably many people here that can guide you.
Good Luck!
