What would uo pick for low end in a 3way running to 300hz max?

The better one or the cheaper one?
Which would I pick? Would be dependent upon how much money I have. If I have lots of money, I would get the better one. If I had just a little money I would get the cheap one. It really is that simple.
Now you decide. ;)
Given the goal is a 3-way, the woofer is not where I'd cut costs.
One big question is power handling, 80W vs 280W, which does give the RS a 2dB advantage in max SPL. However, given that power handling is more of a capacity issue than a run-time issue (i.e. Peak vs RMS), the real difference is bass extension and box size. The RS wants ~2x larger box, but gives you 10Hz more extension; you can get F3 into the low 20's.
I can say this becasue I've been modeling 8" subs ever since PE discontinued the shielded SD215-88. The 215A makes a better sub and actually gives the RSS210 a run for it's money.
Bottom line, both will work, it depends on the power requirements and desired low end extension (and cost).

Actually, the RS225 is also rated at 80 watts (Frank, I think you're thinking the RSS210, which is rated at 280).
I've never heard the SD215. Zaph was not impressed with the distortion calling it "poor, but usable below 500 hz".
Another option might be the DA215, but it's not shielded (if that's needed). On the other hand, it's still for sale.
It's hard to beat the RS225 for the $ when it come to clean bass from an 8" woofer, IMO.
