Short answer: the Topping D50 III. It ranks #1 of 30 DACs by measured performance, rated 4.9/5, at $229; the SMSL D200 ranks #17, rated 4.8/5, and costs $319, so there is little reason to consider the other one.
Why pick the Topping D50 III: Audio Science Review measured 123 dB SINAD, so its noise and distortion are transparent. The tradeoff: Balanced output uses 6.35 mm TRS jacks rather than XLR, so XLR gear needs adapter cables.
Why pick the SMSL D200: Audio Science Review measured a SINAD of 116 dB, so its noise and distortion are inaudible. It supports aptX HD Bluetooth, which the Topping D50 III lacks. The catch: The SMSL D-6S rates the same and measures cleaner at 122 dB for less.
Buy the Topping D50 III. It is rated higher than the SMSL D200 and costs less, which makes it the one to get unless you need something the other one does better.

Topping D50 III: $229.00 Amazon eBay
Pros: Audio Science Review measured 123 dB SINAD, so its noise and distortion are transparent. It packs USB-C, optical, coaxial and LDAC Bluetooth inputs, a remote controlled volume, 10 band parametric EQ and balanced TRS outputs into a compact chassis for an amp or powered speakers. It matches the rating of the Topping D900 for a small fraction of the price.
Cons: Balanced output uses 6.35 mm TRS jacks rather than XLR, so XLR gear needs adapter cables. Bluetooth lacks aptX and AAC, offering only SBC and LDAC.

SMSL D200: $319.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 116 dB, so its noise and distortion are inaudible. It feeds powered speakers or an amp through RCA or balanced XLR outputs, and a volume knob and remote let it work as a preamp. Inputs cover USB, optical, coaxial and Bluetooth with LDAC, aptX HD and AAC.
Cons: The SMSL D-6S rates the same and measures cleaner at 122 dB for less. Its SINAD trails the 123 dB of the Topping D70 Pro SABRE, though both are well past the point of audibility. At 1,214 g, it is a full-size box.
