Should I continue with Bleach?

You do not need to read the manga to know when the fillers start. You can google something like "Bleach filler episodes", and you will find lists of canon arcs and filler arcs. The Bleach anime is however on hiatus for an uncertain amount of time, so I'd suggest you watch the canon episodes up to the latest one available, and then continue from the manga.

I prefer anime over manga also.

You should finish the anime up until it finishes then read the manga where the anime stopped
