Default [Q] Any downside to getting updates on developer phone?

I unlocked my phone through Dreamspark, using my university email. I know that one of the things that I can do with a developer unlock is download and install updates straight from Microsoft. Is this worth it? Do these updates ever decrease the performance of the phone, especially battery life, signal strength, data speeds, and RAM management?

I have a Lumia 520 on AT&T.

Thanks!!
