Is there a reason to pick PT-565 over PT-314?

question in title
these two boats seemingly are the same: same guns, torps, but for some reason they are 2 BR steps apart

am i missing something? or is this the classic case of gaijin balans))

Uh, going off of the wiki the PT-565 has: 2 km/h less forward top speed, 10 tons more displacement, being able to fit 16x 127mm rockets

yeah i can see that myself, i was wondering if there was anything worth the 2 br steps increase

Idk about the objectives in coastal, but if there aren’t any that require the destruction of not-moving targets then not really.
