Not sure if you had a typo, or I'm not following your question.
More wattage capability alone does not necessarily make for a "better mod". More watts are nice but not necessary if you don't need them. Higher wattage mods using an internal non-replaceable battery usually have more battery capacity (mah), which is better from a practical standpoint.
One must also consider the overall build quality of a mod. 100 - 150 watts does you no good if the electronics fail in a few weeks of use, or if its not durable enough to withstand a simple fall onto the ground. You may also pay more for a decent warranty or having the ability to return the mod for repair.
There was a recent thread on ECF where the poster was having an issue with removing his batteries easily from the mod because the batteries were fitting so tightly it was tearing the insulator wraps of the battery and making the batteries unsafe for use. This appeared to be a design flaw for the battery compartment of the mod.
I myself had a Segelei/Ovale regulated mod which used two 18350 IMR batteries in parallel. The batteries also fit very tightly in this mod. The battery compartment used flimsy springs which made loading new batteries difficult without using a credit card to assist. I grew so tired of this that the mod eventually saw permanent status in my dresser drawer.
I personally recommend that you go to PBusardo's You Tube Channel and see if he has done a review of the mods that you are interested in. He does a complete, detailed breakdown of the little things which might be a game changer in your choice.
