I've used both and both have their positives and negatives. Just a little stream of consciousness here...
The individual wrappers are faster if you are wrapping them in the field and not taking them somewhere to wrap in a row. You can stack a TON of individually wrapped bales in a small spot. I could fit 500+ bales in a very small space stacking them 3 bales high. You use much more wrap with an individual wrapper. You can only wrap 22-25 bales per roll on the individual wrappers that I've used where the inline wrapper you can get 75ish bales with two rolls. You need a bale hugger and 3rd vale function on your loader to move individual bales once they are wrapped which can get expensive if you don't already have them. Based on studies I've read you get better/ more consistent fermentation with individually wrapped bales. Inline wrappers need consistent bale size to get less trapped air and good fermentation and sometimes that can be hard baling from field to field. If you are trying to sell hay you almost have to go with an individual wrapper for your customers. I wish I was rich and could have both because some days I love the inline wrapper we bought and sometimes I wish I had an individual wrapper for certain applications.
