I tried both.
MacDrive is a bit flashy and more than twice as expensive as Paragon HFS+. Paragon actually sells a bundle with Paragon NTFS for macOS and some other tools for not much more than MacDrive. MacDrive feels a bit too heavy on the marketing speak.
MacDrive also didn’t seem to do anything Paragon HFS+ couldn’t — and it was only $20. Neither program can read my Time Machine backup, which is no big deal. What’s annoying is that both apps insist on showing the volume in Windows Explorer and assigning it a drive letter. If you click on it on Paragon, you merely receive an error. With MacDrive, you get a prompt asking if you’d like to format it! Not particularly safe.
That went far in helping me make my final decision. In either case, I’m not moving extremely critical data around. If I were, I’m not sure I’d trust any solution out there.
