I prefer Nike half tights...
I've got a couple pairs of the Nike Fundamental half tights. Their fit is perfect and they don't ride up. Also the fabric is thick and quite durable.
They got replaced by a cheaper (same price tho) version called the Nike Fast Half Tight. Though, they the front looks goofy like underwear.
I also have a pair of the Adidas Supernova tight short and they are OK. They don't ride up and are comfortable. Just I don't think they will hold up as long as the Nike.
I must've spent 3/4 of my running career wearing half tights, 3/4 tights, and full length tights. Including speed suits. So I'm quite familiar with running tights. Only time I don't run in fitted clothing is primarily during the summer (unless I've had too much sun).
Now since it's cold, that's all I'm forced to wear is 3/4 or full tights. Only time I put on my running shorts is on the treadmill. Even then, I prefer fitted shorts.
Also, I wear running briefs under all my tights. Like my go-to are the Asics ASX brief.
