Griot's Fabric Protectant vs others

Just wondering if anybody has experience with GG Fabric protectant. Have searched the forum and found quite a bit of praise for Ultima fabric Guard as well as 303 Fabric guard, although that one does not seem to be recommended for interiors. I know there is a lot of GG fans in the forum here, and wondering if it's a good product, or if there are other suggestions out there. I am primarily looking to use it on cloth seats.

I've been using the Griot's for about 2 years. It's been good for me so far.

I use 303 inside and dont see a reason to try anything else for me. Works just fine.

I use 3M scotchguard from the grocery store. Cheap and effective…
