Vitamin C recommendations

I've placed two Black Friday orders from SBRX and then realized I'm running lowish on my vitamin c serum. I'm trying to decide if I should repurchase my current one or try something new.

Currently using Revision and I like it a lot! Vivier CE and Skinceuticals are my other two favorites. I just like to try new products but would happily repurchase any of those. I've tried both Skinbetter ones and they're fine but not in my top 3. I've also tried less expensive brands like Timeless and thought they were just OK.

Is there another brand I should take a look at?? Let me know your faves!
