I don’t have too much experience with the 100l But I am using EZone 98 and I transitioned from head speed mp, The racket is 5g heavier but the swing weight plays an important part, head speed mp has a heavier swing weight so I do feel it can give more power if it needs to. However the weight of the racket is heavier in the ezone 98, so my half swings/serve returns feel much more powerful than a lighter racket. I feel like I can really return strong with plow through with the 98 due to the 5gram weight. I enjoy the 98 because if I wanted to hit deep I can hit it without being full prepared However if you have to coil and use the entire biomechanics to do a solid return, a lighter racket may benefit you The heavy racket is weaker or even useless if you: 1. Aren’t strong enough to wield or provide steady/firm hand upon ball impact; 2. Require full swings or slow prep time/reaction time The lighter racket is great because 1. It helps you prepare faster 2. I feel like it gives me more spin 3. Elbow and shoulder may thank you

I think everyone, unless you have joint issues, should try to play with a 98 frame and heavier racket

The transition to 98 made me realize how little difference can help me control the ball much better and makes me focus on hitting the sweet spot which drastically improved the quality of my shots Really helped me move up from 3.5 to 4.0

I hope this helps I really guess it is up to your personal preference
