the problem isnt whats more effective theyre both very good..the problem youll run into is with the dbells your jumping the weight 10 lbs each week unless you can get a hold of those magnetic plates to reduce the increments..the other problem youll run into is they are a pain in the ass to get inot positon for 5 sets i got up to 105's but it was more of a hassle so switched over to BB front presses..now i can adjust my weight by a smaller increment and dont have to worry about flipping up huge dbells..just my .02
