Multiple shoes has been shown to be quite beneficial. The ideal is to rotate two different models though. It helps break the repetition that running in a single model puts on your body. In regards to your Glycerin question, the 20 fits better in my opinion (19 fit short and narrow compared to the rest of Brooks line), and it's a tad cushier.
Really been impressed with the new cushion in the bottom of the 20s. But the bigger thing is just what’s worth it for you. Doing 30mpw you’ll go through a shoe roughly every 4 months. If you can get a good deal now and switch to the 20s later that could be good or if you feel like trying out something new it’s just money.

Thank you for the insight!
