What would be your pick? And why did you choose that coin in the first place? Your input would be greatly appreciated. Thank you.

Both are convincing - but I think Doge has become less promising after the Elon Musk hype. The decentralization of these two ancient altcoin is one of my considerations if I intend to include them in my portfolio in the future - but I still haven't gotten a good interest in those two altcoin because they are more focused on bitcoin.
I'm all for diversification - but I wouldn't do it with too many altcoins. Doge was definitely one of the ones I was watching the most since 2020 - but I let go of that great opportunity simply because I was more confident and felt safe with bitcoin.
