As a user of HWS/RDS with magnifiers who also has astigmatism, I would say the following...
If possible shoot with the sights, or at least evaluate them, in realistic conditions. If I look through my Eotech inside the house, it can be disappointing. Once out on the range at real distances and in sunlight, it is far better. Keeping the brightness low helps.
I've also found that the diopter on a magnifier works like a set of glasses for me and cleans the dot up immensely so be sure to adjust it to your eye.
If you get over this way, you're welcome to shoot mine.
