I still like cubetutor more than cubecobra actually. But cubetutor is often down or loads slowly, the updates take long (Commander Legends is still not up for example) and there is a relatively high risk that it may be gone some day in the near future, taking my list with it.
But I prefer cubetutor's card filter since it's easier and faster to use and I prefer the drafting and deckbuilding for the same reason. Can't think of anything that cubecobra does better than cubetutor. I assume there are some cool things that are better on cubecobra, but apparently nothing that I have missed personally.
That's why I still manage my cube on both sites and usually I go to cubetutor when I want to look something up or make a test draft.
Here is my list on cubecobra, which is a bit more up to date than the cubetutor list in my sig.
I have a rule to allow up to one rare per section (WUBRG, guilds, colorless, lands), but currently I only use four of those slots. Did this to fill some holes for archetypes I couldn't properly fill with peasant cards. Don't think that qualifies as a true Peasant+ cube since 401/405 cards are peasant legal, I don't see mine as one at least.
