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.
