depends a bit on a few factors , if its just drying a small area this time of year im sure what youve got is doing fine .
If you need to dry a wall of sofa cushions ... or a wet mattress on its side , or some large areas when the ambient temp is not great , having the extra power if a high powered blower or two can make the difference between leaving a job with a damp item or leaving dry to touch .
Of the large snail blowers , the ones with the motor external at the side are lightweight but at 1/2 HP ... not that strong , of the full power 1.5hp ones , the Ashbys B-Air ... is great value at the moment ,

Disadvantage might be the weight if you have to haul them through an apartment complex or whatever .
I never had te big full room dryer thing but its looks even more awkward to handle .
