Gwent-Tracker or GwentUp - which is currently better?

I started using Gwent Tracker but sometimes the overlay just vanishes or does not appear in the first place. Also it does not allow me to retroactively sort my winrate by casual/ranked or just show matches played a certain period or at a certain rank. (For example if I'd like to see how my winrate was since the latest patch, or since hitting a certain rank).

I used the following Hearthstone tracker before and it has some very useful sorting and analysis tools for your matches.

Maybe the developers of the Gwent trackers can find some inspiration für new or improved features there.
