I've owned both.
I was never really happy with the Eltax's. The bass was just too difficult to control - it would boom awfully at certain frequencies and disappear at others - and the treble could be very harsh at times ("Universally Speaking" by RHCP would make them crackle). Add that to the difficulty of getting them to sit nicely on stands and I would say best avoided.
Having said that, with the right music they could sound amazing - Listen to "Yeah!" by Usher and you would swear there was a sub in the room. Unfortunately that is not my type of music, and with anything guitar based they were awful.
The Wharfedales on the other hand are significantly smaller than these, hence they won't go as loud and are a bit light on bass. However, put them against a wall and the bass will come through and it is always controlled - never boomy. The treble also has a lot of control and restraint (perhaps too much at times). Almost anything you play will sound like you expect it to - always silky smooth. Play anything at fairly low levels, and you get lovely rhythm and punch - cranked up, things can start to sound a bit strained however.
They look fine too. I got the cheapy rosewood ones from Richer's and despite having the finish of a 1980's coffee table they look fine on my Soundstyle z2 improved stands (you need a stand with a small top plate btw).
As always, consider what music you like, where your speakers will be and how loud you want them to go. Don't listen to anyone's opinion until you know their tastes and setup.
The Wharfedales are ideal for me as I like detail in bass rather than BOOM, and I listen at fairly background volume levels but they might suck for your needs. I can't recommend the Eltax's though.
