I think Ill be going with the XP3 tho.
I'll just toss in a comment or two, since I have both filters (on different tanks).
My Eheim have run for more than 15 years now, non-stop, with never a problem, nothing. They are very well made, and Eheim has been around long enough that they have a proven track record as very dependable, efficient and reliable. Considering the thousands of Eheims that have been made all over Europe and NA, this is significant.
Rena are relatively new on the market. Thus, their longevity is an unknown. I have had reputable aquarist/store people mention that from the way they are built they will not stand up to Eheim long-term. I've no knowledge with technical matters, so I can't say I agree or not, but given the cost is 1/3 to 1/2 less I would be inclined to suspect they may not be as high-end as Eheim; if Eheim lasts 20 years and Rena should turn out to last 6-10 years, there is not much of a savings over the long term. This as I say is an unknown.
My XP3 on my 115g is running fine, I've had it for just over 20 months now. It does a super job of catching debris from the water; I have to rinse the pads every 6-8 weeks or the water flow rate slows down very noticeably due to the gunk in the pads. My Eheims on similar tanks last 3-4 months between rinsings. All my tanks look clear, so I am assuming it may just be the extra load in the 115g that requires more frequent rinsing of the filter (the Rena is on this tank).
