Why to go for a custom rom on Sprint Htc one M7 M7spr?

  • Less bloatware: Usually Carrier variants comes with lot of bloatware and unwanted stuff.This might hinder performance a bit which might result in laggyness.Custom Roms will have less bloatware or no bloatware at all as a result of which you will notice its performance is much better than on stock Rom.
  • Better performance: Though performance can be increased by controlling cpu and Gpu  with root apps you might not achieve what you want.There is better scope for performance on custom roms as developers implements different mods to make it perfect.
  • Battery life: Battery life is always opposite to performance.Greater the performance least the battery life  you get.In order to get a balance one between them you have to go for custom roms. 
  • Better customization: Most of the apps with root access will work better on custom Roms than on stock Roms.For instance take xposed installer.It offers lot of modules for customization but will work perfectly on custom Roms than on stock one.
