MacFUSE is free whereas Paragon and MacDrive are not, which is why it was recommended first. But you are right, Paragon is a fine choice in OS X, gives you full speed writes to the drive and works wonderfully. I replaced MacFUSE on my system with that and it is great.
MacDrive which costs $30 for 1 system, and $10 for each additional system, gets the job done, no doubt about it, but I am reticent to spend $30 on a driver.
HFS Explorer lets Windows be on parity with OS X in the sense that now both of them can just READ the other's hard drives. The Snow Leopard disk includes a driver for Windows that enables HFS+ Read support. It is part of the latest version of Boot Camp. BUt you are still stuck with Read support.
Based on that information and the improvements that Boot Camp has seen, I would not be surprised if we have Apple supplied full Read/Write NTFS support in the near future, so why waste money now? Just use MacFUSE.
If the OP decides that slow transfer rates are crimping his style, then he should buy Paragon (which for $30 is also steep for a driver, but the latest version includes an HFS+ driver for Windows)
