Is this a riddle? Like, what weighs more? A pound of steel or a pound of feathers.
No not at all, they round off the numbers in 5 digit increments because of silly human mental limitations, kind of like how some recommend changing your oil every year when 365 days is no more relevant than 201 or 402.375 days compared to the driving environment.
Some -20W is a little above, some a little below, but the whole topic is simpler to address than suggested so far, because if you want something slightly higher than 5W-20, all you have to do is substitute one quart of 5W-30. There is no problem whatsoever mixing the two grades of motor oil if your goal is slightly thicker. Granted, slightly thicker, is slight, not really enough to matter.
Personally, I'd just run 5W-30 in summer and 5W-20 in winter but this may be off on a tangent relative to the noise...
I would look into other things like whether the ticking might be due to chain tensioners with weak springs that need replaced (whole tensioner not just the spring, they are hydraulic but the springs weaken and are needed until oil circulates) and if that doesn't solve it, pull the oil pan to see if there are pieces of plastic from a timing chain guide broken and fallen to the bottom. Make sure it's using an oil filter with a good silicone anti drain back valve.
