TL;DR:For best nationwide coverage and consistent fiber speeds choose AIS-3BB; for condo-focused streaming and entertainment bundles choose True. Legacy 3BB’s gaming strengths now sit with AIS-3BB.
AIS-3BB (post-merger) is the best all-round choice for nationwide coverage, consistent fiber speeds, and bundled mobile+home offers; it leads in median download/upload and has the widest reach beyond major cities. True (True Gigatex) is the strongest choice for urban condos and heavy streaming/entertainment bundles in Bangkok and tourist hubs; latency and throughput are competitive in city areas. Legacy 3BB’s strengths—low latency and good performance for gamers—now sit inside AIS-3BB’s footprint, so gamers and suburban/rural users benefit from AIS-3BB’s broader network. If you live in a condo in central Bangkok and want IPTV/streaming packs, pick True; if you need national reach, the most reliable daytime/nighttime speeds, or mobile-fiber bundles, choose AIS-3BB.
