When removing I just wrap, no need to file down.
As an overlay it lasts just as well to me. As an extension I like if but it's different. It's a bit more forgiving. So if I jam the tip of my nail at work it flexes a little to take pressure off my natural nail. So much less painful that way than with hard gel. But it's still super strong, just more forgiving.
*shrug* after wearing both types as both extensions and overlays I honestly see know reason to NOT just go with a soak off gel. YES it would be SOOOOO much more convenient if they had French pink and white builder and sculpting gels for IBD, but performance wise, I really like it. And it's super convenient for practicing on my own hand.
