Doesn't matter if you switch to a different browser on iOS since Apple forces the same broken Safari rendering engine. There's also the issue of not being able to change the default browser app so instead of clicking on a link you have to jump through hoops to copy/paste into non-default browser. Trying to browse on iOS Safari feels a little too much like this...
When it comes to browser I only have four main requirements that it renders sites correctly, stability, fast smooth scrolling and ad blocking for both 32 and 64-bit ARM. Only Chrome delivers. Firefox is a close second. iOS Safari is broken in all four categories. Seems like every other iOS update reintroduces the spinning wheel "problem occurred with this web page so it was reloaded", javascript engine bug that freezes the iPad, MR forum intermittently not rendering properly, etc. Problem is Apple won't fix any of this because of apologists claiming everything is perfect when it's not.
