If you need more total capacity in a Pb system to compensate for Peukert losses then there is greater total ah consumption for a fixed usage, hence the need for a larger regenerative system. Other factors that need to be considered are financing costs over 5-10 years and how much one can expect technology to change. Can we expect the batteries to be cheaper and better in 3-5 years. My usage patterns are for mostly low DOD with an occasional (10 times a year?) 80% DOD. I'm using flooded Pb for my install and if they last 4 years I'll be very happy with the decision.
