KG,
Welcome to TBN!
I have the RR and 3PT basic scraper blade and york rake. For our ground (rocky/dirt/roots) I thought the RR would be good to prep and clean up but with embedded rocks and such it tends to take too much soil and bounce off the rocks losing the debris in the tines. The landscape rake with flexing tines does a better job for my conditions.
The scraper blade does a good job with snow removal, and scraping/leveling and you reverse it a decent job at leveling/dragging. A standard/basic 3 PT scraper blade doesnt do much digging unless you have a tilting (topNtilt) and these are a lot more $ I beleive.
For the driveway I think the RR would do a decent job scarifying and then leveling and if you use the rear of the bucket for leveling or dragging this should do a decent job.
For the woods and other clean up using the RR it really depends on your soil composition - if a lot of rocks/ledge (our case) probably not so good, if mostly sandy/clay/loam and you need to remove underbrush and vines the RR will work well as other attest.
