Essentially argument about which cryptocurrency was superior in past is pointless because Bitcoin performance has proven everything. And just like you I also always prefer Bitcoin as compare to others.
Yes who is able to survive to this point and never fade, even continue to mint new ATHs is the king of all altcoins today.
some of those debates are just part of the past that have now been proven clearly that BTC was able to outperform them all, passing some Bitcoin Forks that even claimed to be better than Bitcoin, but those claims didn't really happen and they all lagged behind and didn't develop anymore.
There are already active second layer solutions for that scenario, and in past we had cases with very high bitcoin fees.
SSD Hard discs are getting cheaper and internet speed increases all the time, so we could see more improvements and forks for Bitcoin in future.
Layer-2 BTC used to be a problem for Bitcoin because the network still uses the main Bitcoin networks such as BRC20 and Ordinal,
The surge in transactions will be crazy if hype such as NFTs and memecoins on the Ordnial and BRC20 networks occurs.
But now that some developers have started making updates so as not to disrupt Bitcoin's mainnet,
some developers are starting to push for BRC-20 activities to be moved to Layer 2 such as RSK (Rootstock) a smart contract-based side chain and Stacks Layer 2 for smart contracts on top of Bitcoin
and for Ordinal now switch to lighter use-cases such as Sats Names (ordinal-based domains), Bitmaps, Rune (a potential replacement for Casey Rodarmor's BRC-20).
The Rune Protocol is also expected to replace BRC-20 in a more network-friendly way.
