Ok, everything so far is subjective an no-one has given a direct comparison, so here's my 2p worth.
I've been using WW7 for the last 10 years, firstly on my A500 all the way through to my present A1200 Tower.
The thing I like about it most is the speed at which it prints to my HP Laserjet 5. Also, its ability to print multiple copies, collating them if necesaary, mail-merge etc.
For me, it's always been very fast and reliable. Spell checking is easy, working just like MS Word does now, with red underlining! Brilliant from all those years ago :-D
