Does it matter? which surge protector....

word… the house is a new house… built in the late 90’s id imagine… no big deal… not my stereo or tv… was just curious as to what the difference was. and if it was worth the 30-40 dollar difference between the 2 units…

next question 1950 joules vs 3200 joules. etc etc… do those numbers really matter?
sorry for the noobish questions, im not an electrician, nor do i claim knowledge in that field lol
