I prefer the fit of the Boston and how it hugs my feet, it feels more streamlined.

Boston 8/9 seems like it's use of bombproof boost with Eva lasts a true 4-500miles they can look worn but the resilient cushion lasts instead of going to a rock and no response. Plus they're 8.5oz/US9.
SL20 are you referring to V2? Another versatile speed trainer ($100) newest Brooks launch 8. Supposedly little softer, curved, and sub9oz
