A common complaint of the TS irons is that the handle gets too hot after a while, so you can't use it for too long.
Does the Pinecil suffer from this limitation as well?
not for me and I own two V1 original models and 2 of the newest V2 models. part of this is Pinecil has the Silicone comfort grip at the end.
I choose Pinecil because it has 3 ways to power on USB-C PD65w 20V, DC barrel up to 24V/3amps+, and DC barrel with any of my tool batteries (18V-21). the older V1 supports up to 21V (but 24 if you do a modification).
V2 tentatively supports up to 28V EPR 140W chargers (pine upgraded all relevant components from V1 original model). I personally tested this it works on Apple 140W 28V charger and other members have Anker 717, anker 737 (28V battery bank), and several other EPR PD 3.1 chargers tested. however officially on the side of the V2 it only says up to 24V 88W (the new shorter tip is only 6.2 ohm unlike longer 8ohm ts100 tips). shorter tip gives higher performance. pine wants to be conservative on what it supports in the specs of 24V 88w, but several of us have already tested with success 28V 140W chargers and batteries ( with 6.2 ohm short tip that is potential of 126W). there is a Video on youtube comparing the speeds. and on EPR 28V, V2 model goes from 0 to 300C in < 3 seconds. "Search Pinecil V1 vs V2"
right now the Pinecil V2 surpasses ts100 on several levels for performance and comfort. it also has little plastic molded feet so it doesn't roll over on the table when you place it down.
