i worry about glass leaking. Silicone isn't strong
I respectfully disagree here. many of us have had glass tanks last 20+ years on the original seals..if properly made a siliconed glass tank is very strong and will last for decades.
I would go with the glass one easily.
yes, it will be a pain to move. my 165g is over 300 pounds but unless you move often, you set the tank in place and it sits there for 20 years.
if you move often you might want to consider a smaller setup IMO.
