Here's my opinion based on my experience with 2 types of painters tape.
When I painted the stripe in my bathroom, I purchased a more expensive brand of tape called Frog Tape because I really wanted perfect lines, and that is what it promised me. My house has slightly textured walls, so that makes it hard to find a tape that is sticky enough to seal off all those bumps.
From this project, I don't think that Frog Tape works any better than just normal blue painters tape. So, in the future, I wouldn't spend the extra money on Frog Tape.
There's my 2 cents on the matter, just in case you have ever wondered for your projects.
