Hi Logan,
Are these the Dobsonians you are looking at?

Both are quality models, for the extra $270 I personally would go for the 12 inch version (both are F/5). I built a dob myself years ago and used it with a lumicon deep sky filter from suburbia and got fantastic deep space views. The links include the specs listing the relative weight of both OTA's and dobsonian mounts. The best telescope is the one you feel comfortable carrying outside to use. The one which you think you would be motivated to carry out regularly would be the best one for you.
Good luck
Mark
