I'll relate things through my experience with the three filters I have. I've used all three in my 17.5" dob which is not far off from your 16". Thing is too, big $ ain't necessarily better. All three 2" filters I have are made by the same company (Omega Optical) even though it has a high end brand attached to it (DGM). Of my three filters, only one is from this 'high end' line. I've put a link to where I picked up each filter from too.
I have a
Hbeta filter, and it gave me the best image I've had of the Horsehead. It is comes from Omega Optical. Great filter, but it is the least used.
My UHC type is the
DGM NPB. Nice filter but really best exploited under dark skies. Different beast from an OIII, and so it should be.
My third filter is an Omega Optical special. As they make filters not just for themselves, but for other brands, they have the means of making really special items. This sees my OIII filter have the added transmission of Hbeta! A typical OIII filter won't show the Horsehead. This
OIII + Hbeta does! This is my preferred filter for use from home under light polluted skies.
I did a side-by-side comparison of all three filters just on two months ago with all the above three filters on the Horsehead. ALL three showed the Horsie. The dedicated Hbeta was the clearest (just remember that the exercise of looking for the Horsie is one of looking for a bugger all difference of black on black), but the ease of viewing B33 was just as easy with the NPB as this OIII + Hbeta filter. Not just my opinion - there were three other people with me that night that all looked through all three filters too. I've had this filter pooh-poohed by supposedly "knowledgeable" folk who never used this filter, but felt qualified enough to dismiss it outright. Sorry, but my opinion of these people has dropped considerably.
Hbeta filters are great, but they don't get used much. They are very narrow with the selection of light that gets through, and are exclusively a dark sky option. UHC filters are more practical, can be used under light polluted skies, but perform best in the dark. OIII's are my choice for urban skies, but are excellent for their purpose in the dark too. Three very different beasties with three very different applications. Not one right or wrong choice, that is something you need to decide for yourself. And certainly nothing wrong with a dedicated Hbeta filter, particularly if you've got the aperture grunt. Even though it won't get used as much as the other two, for what it does nothing else touches it.
Mental.
