Looking for new Filters

Hello there.

I was hoping to get some advice on what filter brand I should go for for my Canon 80D. So far I've been using Hoya screw on filters for a number of years now, but I have decided to upgrade to a square filter set-up. I'm looking at the usual manufacturers such as Lee and Hitech-Formatt, and there is also now Nisi filters to consider (who have been attracting great reviews).
What have been the experiences of others with these particular brands? Any Pros and cons? Are their any other brands I should consider that are of a similar quality and level?

I've been searching for other camera lens filters here: http://www.for-sale.ie/camera-lens-filters and comparing prices on auction and classified ads websites to get a feel for the market. But other than these three in particular, I cannot find any other contenders. So, assuming these are the ones I should short list, what are the thoughts and experiences of others with these brands? And if there are other potential products out there that I should be considering, could anybody give me any pointers?

Many thanks in advance folks.

Camron.

It would certainly help get the right information back to you if you would tell the folks here what you want these filters you are thinking of to DO for you.

I think he's asking which brand rather than specific filter types.

Indeed.

BTW. I mainly do nature, landscapes and occasionally some Makro shoots of plants.
