There are many gel-like sets now on the market. Admittedly, I haven't tried them all but I really do like Gel Lab.
Since I'm partway through my second bottle of each, I can truly give a good review. I've found that Gel Lab works best with Deborah Lippmann polishes. I've gotten up to one week's wear out of Careless Whisper and Modern Love. It also worked well with Tom Ford Nail Lacquer, allowing me a full work week with one mani. I had mixed results with Chanel and Dior polishes.
Gel Lab topcoat provides an incredibly shiny finish, mimicking what I believe gel nails look like (I've never had them). Although I don't get the super long wear, I'm almost ok with buying this set just for the finished product.
I'm also looking to try Butter London's set- and when I do, I'll compare it. Overall, this is the best basecoat/topcoat duo I've tried.
