I'm curious if adjusting flags in Chrome to increase memory usage of the app would help but without a link to the site in question it's hard to say.
The thing with pages full of gifs is if there are tons of animated gifs on the page things will bog down real quick on any android device. Without pointing everyone to the same page all one is going to get is the kind of subjective "my favorite browser works great for me!" responses that we are seeing here already. It's kind of pointless for the OP to be installing random recommendations until people can evaluate if what he/she is trying to do against their own favorite workflows.
