BWV will be undergoing a refurbishment this year, which appears might actually include work on the boardwalk itself beginning in Sep and possibly before which may limit somewhat the use of portions of the boardwalk. Moreover, even if you get a BWV room, you could end up with noise issues in your room due to the refurb of rooms above or below yours that may be taking place at the time. Also, as noted above, you cannot use Stormalong Bay while staying at BWV. Moreover, as a result of covid, pool hopping to any resort was suspended, and that suspension is still in effect with no word yet as to when it may end.
In addition, as indicated by your mention of the BWV 2BR being 10 less points than SSR, you probably mean a waitlist for a standard view 2BR at BWV. You should not have high expectations of the waitlist coming through for a standard view 2BR at BWV for any multi-day stay. Only about 20% of all BWV rooms are standard view and, particularly because of their lower point cost, standard view studios and 2BRs typically book full most of the year within moments after 8 a.m. when the 11-month window opens (at Aulani that happens only to standard view GVs and sometimes happens to the hotel rooms that are DVC). Owners of BWV (including those who lost the battle right at 8 a.m. at 11-months out) create many waitlists during the 11-month window for standard view rooms, and thus, on the waitlist, you could be behind a number of BWV owners, and not just others who got on the 7-month waitlist quicker than you.
As far as the rooms go, the 2BRs at SSR are currently better internally than the ones at BWV. SSR has completed a refurb that included removing the pull-out couches and replacing them with pull-down-from-the-wall Murphy beds which are better (more comfortable) than the pull-out couch beds, Also, SSR added a somewhat less than twin-size Murphy bed that pulls out of a cabinet beneath the TV in the living room. That does not exist at BWV and will not be added in the refurb, but BWV has that cabinet with the pull-out Murphy in the studio portion of the 2BR, while SSR does not.
As far as resorts go, BWV has many advantages (absent any that could be taken away at any given time because of the 2023 refurb). You can walk or boat to Epcot and Studios. There is only one-bus stop and the bus to and from MK does not share with other resorts; for AK and Disney Springs buses are shared with BCV. At SSR, all Disney transportation to and from parks is via bus and there are five different bus stops at SSR, meaning time to and from a park can take longer than from BWV. Also, having a car for transportation to go to the parks does not necessarily make it easier, example: during the morning rush to MK, you can end up in a long traffic jam when you start getting near the entry booths to the parking lot, and then, after parking, you still have to take a monorail or boat from the Transportation and Ticket Center to MK (SSR buses go directly to the park). In other words getting to MK by car from SSR can sometimes take an hour or more.
BWV also has easy access to many restaurants at BWV, BCV and Swan/Dolphin, besides easy access to the park restaurants, particularly at Epcot because the entrance that you would use is to the World Showcase portion of Epcot that has most of the restaurants. SSR has one main restaurant and some quick service restaurants, and walk to any restaurant could be long depending on location of room, likewise for walking to one of two large themed pools. You also have fairly easy access to Disney Springs with all its restaurants, stores, kids play areas, movie theater, and Cirque du Soleil. Views from BWV boardwalk rooms and from the boardwalk (over a lake to other resorts and Epcot), are among the most impressive at WDW. Views from rooms at SSR vary from very good to mediocre. The resort is spread out over a large geographical area with grass, bushes and trees kept in top notch shape, and a golf course, and just walking around the resort can be a very pleasant activity.
My personal preference is BWV, but with rooms not yet redone (last refurb was 2016), and currently unknown noise and full-use risks that might be involved because of the upcoming refurb, I would probably choose SSR (with its newly refurbed rooms) for a 2023 trip in the summer or fall.
