I think it boils down to this........ everyone's phone is different. Yes we all have the same hardware but the internal components are made in batches and within those batches you will have slight variations. Thus all our phones are different. Then you add in those that are rooted and those that are not, all the different custom ROMs out there, etc. All our phones are different.
If you are finding that you are having good performance from your phone and you are currently using a task killer, then good for you. I personally will not put another task killer on my phone. Been there done that, won't go back. I had a task killer and started to experience force closes, horrid lags the whole nine yards. I removed the task killer and boom, improvement. Realizing that I may be treating a symptom, I started deleting some of the apps that I did not need or did not use. Again, more improvement. So if you are having issues with your phone, start with the task killer and then look at some of your apps. Oh and for those who will say "well your issues were from an app you had not the task killer". Both my husband and I have droids. He has nothing downloaded to his phone except the task killer and he also started having the same issues. Removed the task killer and all issues resolved. Based on my droid and my husbands, I do not feel task killers are needed.
Just my opinion.
