As usual @13 Apostles @OmniD4C
They’re both intertwined, so controlling all of time can inadvertently warp space and vice versa depending on how you do it.
The most practical is Meta Space Manipulation, granting you insane telekinetic abilities and control over any force you desire.
On the flip side, the power with the heaviest effects is probably Meta Time Manipulation, granting you incredible abilities over time flow of any location in Creation as well as on any magnitude. Since time, unlike space, is something that constantly flows and is relative, warping it produces unimaginable effects probably beyond what warping space would produce.
It’s hard to say which is the most “versatile,” since they are both a part of a single system (spacetime). “Continuum” refers to the mathematical connection between the two concepts. Therefore, every use of one ability affects the concept of the other (controlling time can affect space and controlling space can affect time).
The most practical for everyday use would probably be Meta Space Manipulation, while Meta Time Manipulation would be useful for fewer situations, but can help resolve those fewer situations much easier than Meta Space Manipulation could.
I say meta time because it was with the help of the time Stone and doctor strange helped say everyone
Both are very versatile and choosing one over the other is really hard.
I will give an example, every one of the two is like Yggdrasil the world tree, so massive in size that its branches cover multi realms, and every branch branches into multiple branches and so on to no observable end. now every branch hangs from it a fruit, every fruit represents an application or ability. now think about two Yggdrasil tree one for Meta-time and the other for Meta-space, and every fruit is unique in effect to its mother tree that other tree can't have the same effect/fruit (though time and space can influence each other). You see now?
Both are unique and very versatile but none can bore the same fruit. so none are versatile more than the other in general, both are equal, but both have a domain to work in, so if your need is related to a particular domain the best is to choose the power that native to that domain.
Have you ever read
Space is freedom
Time is prison

Space is king
Time is emperor
