How much have you spent so far on tripods that have gone into the trash?
What is your budget?
Don't bother with the Benro 0 series legs. I don't know about the other 2.
Personally, I always recommend spending more on your tripod and head. They will last longer than the rest of your gear combined if you get a good one, and it is critical to get it right the first time to avoid all the buy/sell/lose money shenanigans.
First figure out what you want from it. Do you intend to carry it around a lot? If so, you will probably want something light. If not, weight won't matter, and you can save money in that category. You will also want to get one that will go to your eye level without needing to bend down as that is annoying. But it should also be able to go very low for those low-angle shots. Twist locks or lever? I prefer twist. Do you need a centre column that can go horizontal? etc...
Once you've figured all that out, then you will have narrowed down your choices immensely.
Since you mention landscape, I guess that you will be carrying it around. Weight does therefore matter. Something carbon fibre will save weight. I suggest nothing lower end than the Benro 2 series CF tripods. They can be had with the B1 head for around $350, which is already on the very low end of things. Look for the C2680TB1 or C2690tb1 (1 extra leg section, folds smaller but slightly less stability due to thinner last section), those are both very good price/quality.
If you can afford more, I recommend Feisol. I've been using their 3441T for a few years now and it has stood up to quite a bit of abuse. Pair it with whatever head you want (arca swiss-compatible is recommended, something from Photoclam, Induro, Sirui, Triopo, or Horusbennu is good for those on a budget).
Still have more money to spend? Skip Gitzo, and go for RRS.
