Message:I screen grabbed what I saw and sent it along to compare.
For Era Ten, I'm seeing detailed graphics.  Most are a little dark for me and require me to zoom in and out to catch the nuance.
The troubles I saw with Roll20 were relatively minor ... color changes and such.  I think I removed the issue when I removed Adobe Acrobat.  I would guess the Google Toolbar is a problem as well.
I'm running Windows 7 on a laptop with a 32 inch monitor.  I use Chrome but I think Brave works as well.  (Brave gets two thumbs up from me ... ad blocker built in.)
I keep my characters on the SpaceGamer site rather than in Roll 20.  I can easily export them and much of the notes are there.
I prefer Epic Table for the features IronMike shared.  (Multiple Screens that I can control being the most important).  In Roll20, the Card deck is never visible to me.  It's always where I don't need to look or too small to easily read.  (Quibbles.)
Roll 20 has some useful features but it's a different experience. It seems better with showing a room at a time.  Tasha demonstrated it very well.  It's less tactical and more story telling.
I found both Roll20 and Epic table among other tools DO lose your content on occasion.  I would make the graphics and stage them to a folder on my PC.  In the event it was lost, it could be recovered without too much trouble.
Yours,
