As part of everyone, I confess that it's been a long time since I made an on-chain transaction for purchasing something. I only purchase lightning-ly.
I'll join the line, I too prefer LN. Even though on-chain fees aren't that high, I've had more disappointments
* paying merchants on-chain than with LN.
* Things like additional charges for consolidation fees, time-outs because of slow confirmation leading to a refund, demanding a certain minimum fee and still not giving me an instant order, address reuse, etc. etc.
LN has it's downsides too though, especially if the payment doesn't instantly go through and I have to wait for a timeout.
