New top - would you do plastic or glass window?

[Perfectlap]

you have to be VERY careful clearing snow/ice from the plastic top. My rear window was spotless for the first 10 years. I left the car outside one weekend and the snow came down. Then the temps dropped. The next day I went down to dig out. I cleared the snow off the top with one of those snow brushes. it was all sliding off the car in long pieces. cool I thought no need to apply pressure. well the next day I noticed a tiny horizontal gash in the plastic, just the surface, it didn't penetrate all the way. But as time went by it did go all the way through and it gradually went from a 1/8" tear into this t-shaped puncture.
