iOS: Which is the most lightweight browser?

Safari has been very slow on my iPad recently, so I'm considering some alternatives.

My google search brought me some options like Opera Mini and Puffin but I don't like Opera and Puffin is deprecated.

I've been using Orion browser for a while since I thought it was faster than safari but it's so unstable that it grays out about once in 10 minutes.

I just tried installing Firefox Focus (since it says it's lightweight), not sure if it's the best option.

Is there any browser that is as simple as just a tabbed WebView? ( I mean, I'm looking for something dead simple like NetNewsWire for rss that is written in pure swift.)
