Hello everyone!

I am new to this forum and I must say that the community here is great and quite helpful after using this forum as my main website for cube related questions. So, I figured that I should might as well make an account! Not only that, but I have finally decided to splurge some cash and purchase three puzzles that I have my eyes on: DaYan ZhanChi Stickerless, WitTwo V1 2x2 stickerless, and the DaYan Megaminx stickerless with ridges.
Now I have a several questions (sorry! ._.) regarding these three cubes... I apologize if these questions have already been answered, because after using the search function, I haven't been able to find the answer to my specific questions. So if there is indeed an answer to any of these, then they must be in the deep, dark depths of the threads. Either way, I apologize for my foolishness. Now for the questions:
1. Should I choose the GuHong V2 Stickerless over the ZhanChi stickerless? The GuHong V2 is pretty new, so I haven't seen much people talking about it. Especially the stickerless one. If anyone has experience with both, I would be grateful for your input. Please note that I do NOT plan on attending competitions. After explaining why, please vote your final answer for this question in the poll as well just for the convenience of others who are searching for the answer to this question. Thanks
2. If I do get either the Zhanchi or GuHong V2 Stickerless, is the black faced one worth it over the white faced one? Is there a difference performance wise? Im just wondering because I dont know if the black version is a special version or its just an alternate version for cosmetics.
3. Is there ever a preference to use a stickered cube over a stickerless one besides legality in competitive use? This regards to the 2x2, 3x3, and Megaminx.
4. Besides lubing my cube (planning on using Lubix), is modding it essential? What mods would be necessary for my 3x3 and 2x2 in order for their full potential to be brought out? I do not include my megaminx because....well it would be too hard haha!! XD Thanks again everybody! Great website, great community! Look forward to getting to know everyone!
