When two boats share the same hull type — in this case both the Manitou Pontoons 20 ft. Oasis VP 2010 and the Manitou Pontoons 22 ft. Oasis VP 2010 are pontoon designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department — Manitou Pontoons 20 ft. Oasis VP 2010 at 20,8 ft versus Manitou Pontoons 22 ft. Oasis VP 2010 at 22,8 ft.

Both boats share a closely matched power ceiling — 150 hp for the Manitou Pontoons 20 ft. Oasis VP 2010 and 150 hp for the Manitou Pontoons 22 ft. Oasis VP 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 34 gal and 34 gal — so range won't be a tiebreaker here.

Oasis VP 2010 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Manitou Pontoons 22 ft. Oasis VP 2010 could be the deciding factor.
One place where both boats are genuinely identical is tube construction: both run 3 aluminum tubes at 23" diameter.
