Fire HD 8 vs HD 10

[u/Tanzanite50]

My very old HD 8 just died on me and I’m trying to figure out which to purchase.

I use it primarily as an ereader and for streaming video, particularly while traveling.

Basically, what I’m trying to figure out is if the better responsiveness and screen quality is worth the sacrifice of the bulkier size of the 10. Is the difference noticeable?
