It's just me, or did MP3enc 3.1 sound better than LAME 3.97?

It's just me, or did MP3enc 3.1 (by Fraunhofer) sound better than LAME 3.97?
For this, I made a 15-second snippet of "Afrowell" by StephanAXX, encoded to MP3 using MP3enc and LAME and listened.
MP3enc beats LAME (at quality) at encoding to narrowband (8 kbps, 8 kHz, mono) while still keeping the bandwidth at maximum setting.
About the same at encoding to wideband (16 kbps, 16 kHz, mono).

I don't think LAME was really tuned for ultra-low bitrate.
The 8 KHz/8 kbit files: muffled as expected but LAME also has artifacts. MP3enc sounds clearly better cleaner to my ears.
16 KHz/ 16 kbit: very metallic for both encoders. Similar but I'd say that LAME is a worse.

It's funny to compare them with OPUS or xHE-AAC at similar bitrate :)
Wavpack Hybrid: one encoder for all scenarios
WavPack -c4.5hx6 (44100Hz & 48000Hz) ≈ 390 kbps + correction file
WavPack -c4hx6 (96000Hz) ≈ 768 kbps + correction file
WavPack -h (SACD & DSD) ≈ 2400 kbps at 2.8224 MHz
