I've used BSMP skins for over 10 years.
(Formerly known as Climbing Skins Direct, now Big Sky Mountain Products.)

I've never had a glue issue and I've never had to use cheat sheets.
They have marginally less grip than orange Ascensions but glide MUCH better. As in, blindingly obvious when you're skinning next to someone on Ascensions.
The plush is stout and has stood up to the occasional skin over dirt and rocks.
They don't come in lengths: you cut them to length.
Back when they used the rubber tip stretchers, I blew out a pair after a season and they sent me extras right away, no questions asked. They've improved the attachment system since then.
They've always worked well for me and I have no desire to try anything else.
