Apologies in advance for the length here. 
I don't know that there is any single answer to this question....there are so many variables to consider (time, money, storage, etc.) that every perspective will almost certainly be different just due to personal circumstances/preferences.
However, if it helps, I will say that we have been in the habit of changing themes annually since 2007, and I would say that, in my experience, there are very real pros and cons to this approach.
I've listed a few of what I would consider the 'biggest' in each category below:
Pros:
- Creative interest remains high: I never have a chance to get bored, and always get to experiment with new props, projections, music, etc.
- ToTs seem to enjoy it: the general response has been "I can't wait to see what you do next year"
- Party guests: Attendees always want to 'experience' the next party...similar to the ToTs
Cons:
- Storage: it requires a significant amount of space to house enough props to have multiple themes as options
- Cost: Even if you are constructing your own props, materials can add up
- Refinement: everyone can learn from their display each year, but if you don't repeat it, it's hard to implement those takeaways
Having been rotating/changing themes for a number of years, on balance, it has been the right way to go for us. However, I will also say that I frequently consider going with a more 'traditional' haunt that would allow me to really hone, and develop it.
I suspect that in the next few years, I'll probably actually transition to a semi-static haunt that will be just be added to each year, and tweaked over time. I am spending more time each year lamenting my missed opportunities to enhance the previous year's haunt.
Then, as the season approaches, some new theme/concept/element will capture my attention, and I'm glad that I have brand new things to try.
I'm not sure if that helps, but I wish you the best of luck as you try to work through it.
Happy haunting!
