Depends on your priorities.
Most days I might say Poly. It’s hard to get into Trader Sam’s. Easier if you’re right there all day and night. Monorail, boats, and if you self-propel, you can get to MK via GF from there.
If you’re a shopaholic, SSR is Disney Springs adjacent.
If you like feeling like you’re away from everything when you’re a short boat ride to MK, WL is great.
