I don't understand how you can write both of these sentences about the same type of attack. Does a power bash do a lot of damage or not? Frankly, when I use it, it doesn't seem to do ANY damage. And I just got the Deadly Bash perk as well, and it still doesn't seem to be doing any damage. And yes, I'm doing an actual power bash, not just a regular one. I'm still not seeing a difference between regular and power bash.
Read it again.. i said the power bash does much
more damage, as in much more than a normal shield bash. You can even increase the damage done with another perk. However, ive found even though the power bash does do noticably more damage than a normal bash, it still doesnt do much damage compared to using your primary attack. The power bash is only really useful for the improved staggering it delivers, but i find its still not enough. Its much more efficient to combine stand shield bashes with main weapon power attacks. Some people do like the power bash, but i personally dont for the reasons stated.
