The catch
Brother HL-L5210DW
On a long job with ordinary paper, the main tray may need refilling even if you collect the output regularly.
Side by side
The HL-L6210DW is the one if its 520-sheet main tray saves you a regular paper refill or your routine workload goes above 5,000 pages a month, within its 8,000-page recommendation. The HL-L5210DW fits when a 250-sheet main tray is enough and you prefer a lower, lighter body. Face-down output holds 150 sheets on both, so the bigger input does not turn a 500-sheet run into an unattended one.
Before you buy
Say you are printing 500 single-sided handouts to prepare for a class or meeting. The 6210 main tray takes all the paper in one load, while the 5210 main tray needs two. Both output bins, however, hold only 150 ordinary sheets, so on either machine you have to collect pages during the run. The reason to buy the 6210 is to skip the input refill and not to walk away from the whole job. If you print those 500 pages duplex, the sheet count drops to 250 and the input advantage changes.
Where this comes from
With 20 lb paper, 500 single-sided pages take 500 sheets. Main-tray loads work out to ceiling(500/520) = 1 and ceiling(500/250) = 2. Both printers produce ceiling(500/150) = 4 output batches, which means at least three interim collections. When 500 pages print duplex, 250 sheets fit either main tray. The MP tray is kept for alternate stock.
The catch
On a long job with ordinary paper, the main tray may need refilling even if you collect the output regularly.
The catch
Output bin size stays the same despite the larger main tray. The body is 1.3 inches higher and 5.7 lb heavier.

More paper fits in the HL-L6210DW within the same footprint, yet output holds at 150 sheets. Compare refills, cabinet height and what comes in the box.
These are neighboring Brother business monochrome print-only models, with the same base dimensions and the usual network connections. What a buyer really has to work out is whether the larger paper supply changes the daily job enough to justify the upgrade.
Which one fits
The 6210 spares you the input refill. Both still need output collected partway.
It comes to 250 sheets, and either main tray holds that at the stated paper weight.
That is over the 5,000 recommended maximum of the 5210 and within the 8,000 of the 6210.
The 5210 stands 1.3 inches lower. Before putting either under a shelf, check operating clearance.

The MP tray is kept for alternate stock.
A shared office might have plenty of floor or worktop space but little clearance beneath a shelf. Both printers share the same 14.7 by 15.3-inch base dimensions. The 6210 is 1.3 inches taller when closed and 5.7 lb heavier. If you seldom have to refill the 5210 mid-job, its lower body can be the better fit. If you refill every day and have the height to spare, the 6210 adds capacity without getting wider or deeper.
11.4 - 10.1 = 1.3 inches and 29.8 - 24.1 = 5.7 lb. Operating and ventilation clearance is not part of the closed dimensions. The packages compared are the standard single-tray DW ones. DWT packages are left out.
If you are upgrading to avoid buying toner early, look at the cartridge that ships in the box. Both standard boxes include TN920 with the same 3,000-page ISO claim. The higher-capacity replacement for the 6210 comes later and is bought separately. It can still suit an office with sustained high volume, but a light-use home office does not start out with six times as much toner. Compare current complete costs before the replacement-yield headline makes the decision for you.
Each ships with a 3,000-page ISO19752 TN920. The HL6210 can also take an optional 18,000-page-rated replacement. No current cartridge cost, household yield or saving on ownership cost is assumed.

Trade-offs
Change of plan
Go with Brother HL-L5210DW. The 5210 spares you from buying capacity that removes no regular refill.
Go with Brother HL-L6210DW. Those specific capacity and workload limits are what the 6210 addresses.
Neither model fits. The documented output bin on each holds 150 sheets.
Decision guide
Printing a long packet while you work on something else is the goal, but a larger input tray may fix refills and still leave you collecting printed sheets.
