That is a matter of opinion. I actually don't use my kindle anymore, having gotten annoyed with it way too many times and haven't tried any alternative browsers but if you can get chrome or dolphin on there they are both much better than silk in my personal opinion.
I'm guessing you're a new user so I'm gonna give you a couple friendly tips about xda
1. Don't ask for ETA's, that means don't ask "when/will there be an update for *anything*" the devs do all their work in their free time and don't exactly get paid for the numerous hours spent making ROMs/mods, cracking security, gaining root access.
2. Matters of opinion are not generally acceptable posts or questions because "what is the best..." Is based on personal preference and the threads quickly deteriorate into a pissing contest
3. As stated, be more specific when making threads
4. Before asking a question browse the forum and use the search function. Not only does it prevent multiple threads on the same topic but you often find your answer faster that way.
Welcome to the forum! Good luck not using the kindle to kill yourself in frustration, lol.
