Gel X vs acrylic?

Hey everyone, I can’t get my acrylics to last more than two weeks. Basically, as soon as I hit the two week mark, they start falling off. They lift from the bottom. It’s always like this wherever I go and whatever nail tech I use. Sometimes I’ll even start coming off after about a week.

Right now, I have a nail tech that I really like he does a good job with shape and designs. My nails last the two weeks that I expect them to, but I would love for them to last longer, as it is expensive. My nail tech was recommending gel X and telling me that they would last longer than acrylics, but everything I’ve heard is that acrylics last the longest.

My appointment is tomorrow. I’m going to try the GX, but just wondering what other peoples experiences are ?
