Not when the simple answer to the question is "yes, because they work"
"work" is relative. ive said many times that they are capable of maintaining water parameters, but as any filter, (or even no filter, as bacteria will grow on the surface of the tank/decor/substrate) is capable of doing the same thing, what "work" is it really doing?
I read the thread, thanks for asking though

I'm not a noob when it comes to answering questions on a forum. What I still have to ask you is have you tried using one? So far it seems to be a no since you've given me no other reason to believe that you have. You can't truly say product A is better than product B when you've only tried one of them...
it only "seems" no, if youre foolish enough to ASSume that you have any clue about my personal experience. like i said. go find a post that says i have no experience. ive never once said that. and since ive had to repeat that to you a few times now, i guess that means youre not capable of deductive reasoning. probably why you chose to ASSume such ridiculous things, rather than focusing on the facts.
So far you've said:
1) They're hard to clean - not true
wrong. the plates make it much harder to vaccum the substrate than it is without them. thats a pretty simple fact.
2) You can't have live plants - not true
having a single crypt or some java ferns tied to a piece of DW, is NOT the same as having a PLANTED tank.
3) You can't have sand - I will give you that one.
no need to "give" me anything. like i said. the facts speak for themselves.
4) Almost every other filter is better - that really depends on the person and their tank.
how so?
if a filter does the exact same thing for cheaper, its better.
if a filter does more for the same price, its better.
if a filter provides the same biological filtration, plus mechanical filtration(and chemical if you need it), its better.
again, speaks for itself.
Now the OP is
currently using one so obviously the cheapest way to go about things would be to leave it as is...that is, unless its causing some major problem. If it aint broke dont fix it...
the OP also said he has a 7" jaguar cichlid in the tank, which again (its sad i have to repeat this, when you claim to have read the thread) will dig up and move the substrate, exposing the bare plates and greatly decreasing the effectiveness of the plates.
btw, he also said he has 2 HOB filters as well.
