Shopping for parts

[lotech]

I've been doing a lot of research before I start buying parts.
Is there different types of extrusions?
Seems like someone mentioned V-shaped and T-shaped?
Will both work or is one better?
For instance, what would this be called?:

These are Misumi extrusion clone.

There are roughly three commonly used types of extrusions:

1. Misumi extrusions, including Misumi and similar cross-sectional clones. However, it should be noted that some of these clones allow Roll-in nuts to slide in easily, while others require tool insertion.
2. European extrusions, which differ mainly in the size of the tapped holes (M6), you need use M6x16 BHCS screws with it. .
3. V-Slot profiles, cannot be used for VORON .

Thanks for the thorough answer.
I saw the V shape on the ends and thought maybe it isn't something I want.
I bought a set in red.
First time I've bought from alley express.

I have a list of shtuff to get from west3d.
Their self-source configurator really helped figure out what I need.
