Slightly different vehicle but, I put KYB Excel G gas strut assemblies on all four corners on my 09 EXP.
Installed myself and had the dealership do the alignment.
After much research online and thru mfr. websites, it seemed that the Monroe's would give a softer than stock ride and the KYB's a firmer than stock.
Based on my experience with Monroe's on a different vehicle I would agree. After 70k, still very pleased with the KYB's. Got 'em at Rock Auto while they were having a rebate program.
Probably a little more expensive for the full strut assembly vs individual components. But, all I had to do was remove and reinstall the new without having to fuss with a spring compressor.
If you have a jack and jack-stands, it's a simple afternoon job. Many videos online to walk you through the process.
If I remember correctly, the only tool I needed to rent from Autozone was a huge torque wrench and socket to remove the front CV/axle nut.
