mats vs. tile on a sloped floor

[Skrutinizr]

I've been anxious to do my floor, but there's a central drain and the floor is sloped towards the drain. My concern was tiles wouldn't form to the floor, but a mat would have to be done in two parts (it's 20x24) and if the mats form better to the floor, there would be a gap between them in the middle.
How does one deal with this? I'm going to try to measure the slope, but I would guess there's probably 2"-3" or so difference compared to a flat floor. The end result may be doing one half of the garage with a mat, then painting or tiling the other side.

not sure what type of 'tiles' you are considering, but RaceDeck's PowerLocks will allow the floor to contour to a slope and stay engaged.

Here is the situation. Polypropylene tiles do ok on a slope if the slope is consistent. If there are slope changes it is going to depend. The mats, or even PVC tiles (to an extent) will contour to the floor. The drain can be covered and the mat slightly altered to achieve drainage through it. There are a couple of methods... From cutting out a circle to drilling 1/4" holes...

You would not have to gap the mats, you could use two 10x24 and a center strip. Here is a link to my wife and I installing in our garage

The whole floor resembles basically a bowl, albeit a shallow one. It seems they formed it fairly well, so it's truly not flat anywhere. I'll get some measurements and do the math on it.
Initially I was thinking PVC tiles with a + pattern of perforated tiles that meets over the drain so there are essentially four drain paths.
