Size, drawn to scale

Both amplifiers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.

One scale for both, aligned at the back panels the way they would sit against a wall, so the deeper one visibly stands further out.

Michi X3 Series 2 needs about 14% more shelf area.

Inputs and Outputs

Balanced connections

Both have balanced XLR connections. A balanced cable carries the signal twice, on two conductors of opposite polarity. Interference picked up along the way lands on both equally and cancels when the two are recombined at the far end, so the longer the cable run and the noisier the surroundings, the more it is worth. Whether it also yields more power depends on how the amplifier is built inside - some are balanced end to end, others convert to single-ended internally and deliver the same either way.

Verdict

Both are Michi, from different ranges - the engineering approach is shared and the differences are mostly in power, connectivity and price.

Area	Better	Why
Power	evenly matched	Effectively the same output - 235W against 220W into 8 ohms is under 1dB, which is not an audible difference in loudness.
Grip on hard loads	evenly matched	Both behave much the same into 4 ohms - output increases strongly (350W and 340W).
Noise floor	B	Michi Prestige X430 is the quieter design on paper - 105dB against 102dB. Audible mainly with sensitive speakers in a quiet room.
Built-in DAC	A	Both decode on board, but only Michi X3 Series 2 handles DSD and MQA.
Streaming	evenly matched	The same streaming platforms and services on both.
Use with a TV	depends	Only Michi Prestige X430 has HDMI ARC, so the television can drive it directly and one remote controls the volume. If the system is for music only, this changes nothing.
Room to grow	evenly matched	The same expansion options on both.
Price	B	Michi Prestige X430 costs less - $4,999 against $7,499 at list.
Watts per dollar	B	Michi Prestige X430 is the cheaper watt - about $23 per watt against $32. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output.

A Michi X3 Series 2 B Michi Prestige X430
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both amplifiers are judged; anything missing on either side is left out rather than guessed.

Which should you choose?

Michi Prestige X430 has the edge on paper, though not by much. The rows marked "depends" are more likely to decide this than the score is. If this sits under a television, Michi Prestige X430 is the one to buy - HDMI ARC means the TV remote controls the volume and there is no second box in the way. Think about the whole system: the roughly $2,500 saved by taking the cheaper one would buy better speakers or a subwoofer, which does more for the sound than the difference between two competent amplifiers.

What a spec sheet cannot show: how either sounds with your speakers, how the controls feel day to day, and what the app is like to live with - which is where most all-in-one amplifiers are actually won or lost. Power figures are the manufacturers' own and are not measured to a common standard, so treat small differences as noise. If you can hear both, that will tell you more than any row above.
