Recommendations for Watch and HRM (Swimmer)

Hi! I am in the market for a new HRM and watch. I have been eye-balling the Forerunner 165 and the Pro Plus HRM but I would love some feedback on both of these. Would these be good choices for someone who primarily swims but also does hot yoga and other gym based classes? The HRM is primarily for the pool. Garmin discontinued the Swim HRM but I keep seeing it recommended which is frustrating because I don't know what to pick. Needing something that will hold up but also withstand whatever this beleaguered teacher (swimming for her sanity) throws at it. 😅🤣
