There are a couple of things to address here, the main one being that there is no tripod that will tick all the boxes you require.
Are you buying a tripod with the hope of using it for stills and for video?
How serious are you about video?
What kind of travelling do you intend to do?
Would you consider a tripod system, rather than one single tripod?
A little bit about video tripods:
Video is almost always shot in landscape orientation. As such you are going to struggle to find a video tripod or tripod head that permits shooting with the camera in the portrait orientation (lenses with tripod rings get round this, but this tends to be only telephoto or telezoom lenses)
If you want something that will do both stills and video well then I'm afraid it means you are looking at two tripods, or at least two tripod heads. There are video / stills heads available (i.e. manfrotto 390RC) but they tend to be basic and / or compromised.
A good video head will have fluid dampened movements the resistance of which can be altered (drag), a sliding plate for positioning and balance, and ideally some form of counterbalance to permit the smoothest of movements.
I bang on about counterbalance all the time, when you've used a properly set up counterbalanced tripod you will be amazed at how little effort is required to move even very heavy cameras and much easier it is to get smooth ramping into your pans and tilts.
Ideally a good video head will sit atop some form of levelling device, this is most commonly dedicated video tripod legs with a bowl or minibowl mount, but can also be a special column or a levelling head between the tripod and the video head.
The benefit of this is that you can quickly set up a level base to ensure that the camera stays level throughout your pan. With a conventional tripod such a set up can be time consuming and frustrating.
There are some video tripods on the likes of amazon which on paper seem to tick the above boxes for reasonably low prices, I have not used any and so cannot vouch for them, there are some who use the forums who have and who may wish to offer an opinion here.
I use a couple of tripods, one built around a set of Manfrotto 055 legs with a 438 level head and a 501HDV head. This is large, heavy, but gives a great low and max height, and the head can be easily switched for a stills head or my timelapse panning head when required.
I recently got hold of a Sachtler Ace, which ticks all the boxes and gives the smoothest movements I've used on any tripod aside from the adult Sachtlers I use with ENG cameras. The benefits of the ACE is that it is reasonably compact (in video tripod terms) has an excellent counterballance system which is staged to suite DSLRs to HDV type cameras, and has steppable drag so you can repeat movements easily.
It isn't the cheapest on the market, and it really isn't stills friendly at all, but it is very good and despite the higher price, excellent value. You get everything you need in one box (including bag) the MS version is more practical for outdoors use (mid level spreader)
So that is the two options I would recommend..
Manfrotto 190 or 055 legs (190 more compact, lighter, cheaper and up to job for DSLRS)
Manfrotto 438 leveller
Manfrotto 501HDV (or ideally the newer MVH502 head)
Add in a stills head (804RC2)
and you have a decent versatile system, or a Sachtler ACE, for video only, which works superbly out the box.
The cost of each option works out about similar, maybe the ACE is a little more expensive, but it's what works for my DSLR kit.
