To implement a plan: Te
To point the countless pitfalls in the plan: Ti
A man builds. A parasite asks 'Where is my share?'
A man creates. A parasite says, 'What will the neighbors think?'
A man invents. A parasite says, 'Watch out, or you might tread on the toes of God... '
I mean, Te's pretty nice. It's not perfect, but it has momentum and a delightful simplicity to it. I read other people's posts about their experiences as a particular type, and think I got pretty lucky to have it as a dominant function.
Having said that, if I was gonna have "function envy" about any of the others, then it would be Ti. Ti-primaries and secondaries just seem to have more fun. They have cooler toys. They fight crime. They can read xkcd without needing Google to understand the jokes. It's like where does it end with these guys?
I admire/am frequently struck into awe with the depth of logical consistency of Ti. But no Ti users impress me or make me happy (one of those? both? both sometimes?) except when it's suuuper strong in INFJ's and at the expense of Fe because 1) I'm a J type and need closure, and 2) I've yet to know an ISFJ with a strong, especially strong-at-the-expense-of-Fe, Ti that was impressive (seemed to be common sense type stuff the abnormally heavy ISFJ was pointing out? but it was definitely Ti)... so I guess I need the theorizativeness of N as well (I'm N). INFJ's Ti feels like sharp Ti though, and I dig it. INTP's are too listless, ENTP's are too jokey with theirs, ISTP's tend to more base theorizing, I'm going to leave out my opinion of ESTP because this is getting too long and no one cares anyhow.
I'm a Te user. Ti just drains me to use it, but I'd wish 1) it didn't, 2) I had the motivation to use it, 3) I had something to use it for (I'm not academic or intellectually curious)(If I had situations where it'd be good to use it, #2 would be taken care of as well). I remember once I had a couple weeks period of spontaneous brilliant, quick, and non-energy-draining Ti usage, and it felt awesome. Beebee or whoever says, I think, for my type, Ti is the "Discovery" role? And I agree, that period felt like a period of great mental growth, expansion, inner discovery. Te just is for me, I don't view it as special or a special power nor does it do anything special for me, but I don't think negatively of it - it just is, for me (for some Te doms I can see the domination and power, among other similar things, it gives, though; I think the issue is it being in the dom position, though).
Edit: As others said, which is "better" depends on what your intention is.
I may be a Ti-user, but I can use Te. I just prefer the Ti style of thinking. When I go into a Te-style mode though, it doesn't affect me a whole lot differently than Ti.
I get drained speaking too long with HEAVY ti users. It frustrates me to no end if I feel we are covering a bunch of crap that most likely will not be a real issue. There has to be some balance for Ti that's weighs probability quickly. Help them separate the fluff from the important stuff without trying to account for every little detail.
Ti kind of reads like Si sometimes when working together with someone.
