What kind of flooring do you use/recommend?

[Bob S.]

Long term rental hold. 20+ years.
In Texas, 2 story house with plywood upstairs. 

Had one flooring store recommend glue down, they said this is better than 20mil 5mm snap in LVP flooring, as the snap ins sometime break and you can easily replace a glue down.

Another flooring store recommended "loose lay flooring" basically that is similar glue down, but has sticky material on each board. 

What are your thoughts? We decided to go with 20mil 5mm LVP waterproof.
