TweetYour DB incline bench is going to give you a greater range of motion and cause the use of more stablizing muscles since each arm is independent. Thereby, the DB movement is more effective at targeting the chest, anterior delts and triceps. If you're concerned about your triceps burning out then isolate your chest first with a DB fly or similar movement which requires predominately the chest muscle. Then when you start your compound movements (i.e. bench, DB bench, etc...) your triceps should be fresh. My 2 cents.
