So my point once again, if it is not cheap, shy not get something that is more permanent?
That is probably a personal decision.
-- If you like the soft feel on your feet, you may prefer it for that reason.
-- I think I remember it is cooler on one's feet than some of the harder plastic teaks. That may be another reason to prefer it.
-- It comes in different looks and patterns and you may prefer one of them to the looks and patterns of other teak systems
-- You'll have to do less prep, which may be a plus, w.r.t. boating time vs project time balance
-- It is probably less expensive per install, especially all in, which may be a plus if thinking about the "today" cost.
-- It'll be faster to install (whether you or a contractor), which may be a plus, w.r.t. boating time vs project time balance
-- It doesn't require special tools, such as miter/chop saws and trim saws, (or seam welder's, if you'd like to avoid caulking planks), which may be a plus, depending upon what you or your contractor already have
-- If done in small sections, it may be more repairable in the event of something major that would damage either.
On the flip side
-- You may prefer the look of the patterns that a different, harder product comes in
-- You may prefer the firmer feel under your feet
-- You may enjoy your boat more and worry less with a harder teak, especially if small defects bother you
-- You may want to "do it and forget it" vs think of it as a maintenance item
-- It may cost less, especially over time, to go with the product that lasts longer, especially if you keep your boat for a long time and pay others to do the installs.
Etc.
There are trade-offs both ways, I suspect.
