revival... but since I've been testing a bit between similar rubbers, I'd like to share.
I have experience between TG2 and H3 in commercial, neo, and provincial blue sponge iterations. Also, H3-30and S3-60 versions.
In all variants, to me- skyline has more spin, and more feel from the thinner top sheet. H3 has longer throw and higher speed potential (shines in counter looping). I feel much more control with Skyline, but it's noticeably slower than H3 for me.
Serves, pushes blocks have a ton of feel with TG2. I feel like if spin and control is your forte- choose TG2. If speed is your need, choose H3 (or TG3?).
I have larger strokes, so I tend to prefer TG2. If you have smaller, more efficient strokes, I would think H3 would suit you more.
