the answer to your poll is whichever one feels most comfortable to you.
The answer to the actual question at hand is to be less precious about your art.
There's two schools of thought when it comes to comics:
1: each page is a finished work of art and should be appreciated as such.
2: Each page is part of a larger whole, and the individual images are meaningless without the rest of them in conjunction.
This is a sliding scale, not a binary, you can be right in the middle or lean towards one side or the other or be firmly in a single camp.
If you lean towards 1, then who fucking cares how fast you are? Make each page beautiful and incredible in its own right. That takes as long as it takes, and everything should be as perfect as you can make it.
If you lean towards 2, then the solution is to be less precious about your art.
Trying to draw a circle and the lines don't quite match up? Who cares, move on.
Doing some cross hatching that isn't perfectly aligned? Who cares, move on.
One eye is slightly lower than the other on a background character that isn't actually a focal point in the scene? Who cares, move on.
I feel physical pain when I watch artists take 5 minutes to draw a single curved line because it doesn't line up 100% perfect with the underlying sketch, so they CTRL+Z, redraw, CTRL+Z, redraw, CTRL+Z, redraw, CTRL+Z, redraw, over and over and over again.
The 'Undo' function is a tool, not a crutch. Do not become dependent on it.
99% of those little mistakes that make you a slow artist DO NOT ACTUALLY MATTER. Nobody, and I mean nobody except for you is actually going to notice them.
Let your sketches be loose and messy; focus exclusively on form, perspective, and composition when penciling. Trust yourself to figure out more details than you think you can in the inking phase. You might surprise yourself.
Line doesn't match up perfectly with the sketch underneath? Who gives a shit? what you need to ask is: 'Does this line look good and communicate what it needs to communicate?'. 99.999% of the time that answer is yes, even if it doesn't line up as well as you think it should.
If you lean towards number 2 and you want to be faster, then you need to understand that your art is not some precious little baby that needs to be polished to perfection, it is a small piece of the pie. A cog in the machine and nothing more, so get it to where it works, and then move on to the next cog so you can get that machine up and running.
Oh, and also, don't zoom in. If it isn't visible at 50% zoom on your screen, it will never, ever be noticeable in a finished/published version, be it print or posted online. If you ever zoom in above 50% zoom, limit yourself to 10 seconds before you zoom back out at most. Do as much of your art as possible from a reasonable view, otherwise you will get lost in the weeds for a bajillion years on pixel-by-pixel perfection.
