DCF唔係想像中咁美好, 唔好神化佐佢, 最主要佢係無彈性同埋non rip-stop.Pack埋都好大舊下, 仲有風打落下比較嘈同埋真係好透光。

From Dan Durston
The two main reasons for opting for DCF over silnylon are (1) much lighter and (2) no sag.
The good reasons for opting for silnylon are price, durability and packed size.
DCF isn't going to last longer than silnylon. Yes it's very strong but it's also not very abrasion resistant nor good at repeated packing/stuffing. At best you'd get an equal lifespan but my money is on silnylon to last about 2x as long. Also both materials are typically plenty waterproof (some low quality silnylon exists, but any good company is using good stuff these days) so I wouldn't worry about this.
The sag of silnylon is a notable con but how much of a problem this is depends on the material (some nylon expands more than other nylon when wet), the tent design (larger panels show this more) and how easily you can adjust the tension. For a simple one pole pyramid, the panels are large so sag is noticeable but if you are using an adjustable trekking pole where you can easily reach out and extend the pole a couple inches then the sag isn't a big deal. It's more of a problem in a tent with multiple poles where you'd have to get out of the tent to adjust them, or if you're using a non-adjustable hiking poles.
If all you care about is avoiding sag, then you would be well served with silpoly which largely eliminates that. So really the only good reason to opt for DCF specifically - and it is a very good reason - is that 0.5oz DCF is much lighter than anything else.
