Are there solid benefits in switching from standard MBR to GPT? Now that I have Windows 10, I'm wondering if I should do it. I have no need for more partitions (currently 3 drives with 1 primary partition each) or partitions larger than 2TB and likely never will. But I'm curious if there are other good reasons why I should make the switch and give up some SSD space for the couple of small system partitions that would be added. Is UEFI booting necessarily better?

As far as I know, you cannot just change from one to the other. You have to wipe all partitions and reformat the hard disk. I don't believe this is what you want. If I remember correctly, there is a 4TB limit on MBR, so in 6TB or larger hard disks you either split to 4TB maximum partitions or you have to choose GPT when initializing the hard disk. I don't think there is any performance difference between the two, I might be wrong though. Also if your system boots fine as it is then avoid messing with EFI etc or you might not be able to boot from DVD or other device. If it works, don't fix it, as they say.

Partition Wizard can do the switch from either to the other. I'm just curious to know if there is sufficient benefit in GPT other than additional partitions and partition sizes to merit changing. The more I see, the more I'm thinking no.

I prefer MBR for backwards compatibility. I would not bother in your case IMHO. I usually work with PE or Linux livecds and the such and there are a lot of trouble trying to change/repair GPT partitions.
