Short answer: both are discontinued, so this only matters if you are buying used. Used, the Thomann Swissonic A306 is the better pick: it ranks #54 of 119 powered bookshelf speakers by sound quality (rated 4.3/5), against #97 (rated 3.9/5) for the KRK Rokit 8 G4. If you want one new, the KRK Rokit 8 G5 replaces the KRK Rokit 8 G4 and is rated 4.0/5 at $1,076.
The Thomann Swissonic A306 is the better-sounding pick. Affordable studio monitors with useful bass and tone controls that make a capable budget setup when carefully tuned. The catch: The published result is not the flat-control setting: it specifically uses -2dB treble.
Why pick the KRK Rokit 8 G4: An 8 inch studio monitor with balanced inputs and room adjustment, for listeners who want more scale than a compact monitor. The tradeoff: The large cabinet requires substantial desk or stand space.
Buy the Thomann Swissonic A306 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the KRK Rokit 8 G5, which replaces the KRK Rokit 8 G4.
