Subaru's Lineartronic CVT has proved to be reliable.

As for sucking to drive....well....that is preference. I think they are fine.
Nope. CVTs offer zero benefit in efficiency over a modern DCT or automatic. Comparing it to Subaru's previous horrible 4EAT is disingenuous.

Ford was an early(ish) adopter of CVTs but they've dropped the use of them entirely. Their PowerShift DCT transmissions offer better gas mileage than a CVT would. CVTs have the benefit of wider ratios, but they do not lock up anywhere near as tight as a DCT or modern auto. They are quite a bit more lossy than you'd expect. Most manufacturers are going with modern automatics or DCTs over CVTs.
