IMHO both of these setups would be high light. I have never heard anything bad about either of companys. Maybe if you don't mind building a canopy for the tank you could check out www.ahsupply.com
and make something custom.
Sorry I couldn't be of more help. Hang in there because I know there are a few 46 bowfront people that participate in this forum with nice tanks. I am sure they will have input when they see your post.
