If you mean modern Trek Madone style, I have the Panda Podium x Ahyka set for my Winspace and they are fantastic. Really clean design, integrate well with the frame, well made and the black with gloss logos looks really premium. Because I liked them so much I got a second set for another bike - but this time just the Ahyka bottles from AliExpress. And even though ostensibly they are the same, they just look and feel cheaper. I'd have no hesitation to recommend the Panda Podium versions, and not sure if the AliEx versions were fakes, but the cost difference was small enough if I wanted a second set I would just go back to Panda Podium.
If you want a more traditional Elite Chrono style TT bottle, I've got an original Elite, and an AliEx clone that works using magnets, and I prefer the AliEx version. The cage on the Elite never worked that well - the magnet is a bit bulkier on the AliEx bottle but an easier process to slot back in the cage. They don't hold very much, and really only integrate well with the down tube meaning they look a bit off when using two, so I think they are more suitable for TTs where you are more interested in using the bottle as a fairing rather than drinking very much out of it.
