Forget the $200 Monster and its "designed by Richard Marsh" advertising copy. The TrippLite Ultra is fully equal to the MP 1100, and may be superior in its isolated plug outlets and RF/EMI noise suppression. There are limits here: Technology in these small boxes can carry noise suppression level only so far. The next big step is a balanced power transfomer.
If you're a homeowner and concerned about future SURGE damage, particularly from external lightning field/strikes, it may be better to consider a service entrance or whole-house surge suppressor for less than $175 incl electrician's installation.
