Depends on the controller. Typically only the higher end controllers will do RAID 5, thus in a sense, RAID 5 might be easier to recover from (as theres no shortage of pathetic RAID cards that are great, until the array degrades).
On that note though, from a technical standpoint, RAID 1 should be easier to recover from (in most casesm you shouldn't even need to recover, you should be able to pull the working drive directly from the controller and drop it into the system), though with bad RAID cards, thats not always the case.
I can recall a highpoint controller that a customer had doing raid 0+1, he lost one drive and the array was permanently stuck in degraded mode. Countless hours were spent after inserting a new drive trying to rebuild to no avail, firmware upgrades, etc. Needless to say, he replaced it with a 3ware card (much nicer) and we 'fed' the old one to the elevator (The elevators have no 'touch' sensors in 151, and will crush most small objects with glee).
