The competition over layer-one supremacy is heating up as we move into 2025 and beyond. Inside that grouping, SUI and Avalanche (AVAX) are two of the most closely watched names. Both provide high throughput, low cost per transaction, and are rapidly developing ecosystems. Investors are assessing their relative strengths as they prepare portfolios for the next market cycle. But the analysts warn that established projects like SUI and AVAX might not lead to the truly exponential returns–the kind that can only be won elsewhere, in cultural tokens that retailers can catch fire holding.

SUI: speed and developer appeal
SUI has positioned itself as one of the highest-speed Layer-1s, able to accommodate thousands of TPS at near-instant finality. Supported by Mysten Labs, move progrmaming language it has been created to be a part of the on chain solution to to allow parallel running and scalable dApps.

The developer community has grown rapidly in 2025, and more and more DeFi protocols, NFT platforms and game projects have been deployed on SUI. 30-day active addresses and total value locked (TVL) are also seeing consistent growth, propelling it as one of the most notable Layer-1 competitors in the space. Analysts believe SUI could rise from its current $3.1 level to above $5-$7 in the best scenario in the coming years.
Avalanche (AVAX): scaling through subnets
Avalanche has maintained its reputation as a high-performance blockchain through its subnet architecture. This approach allows developers to launch customizable blockchains under Avalanche’s umbrella, each with independent validators. It’s a model designed for scalability, flexibility, and enterprise adoption.
In 2025, Avalanche continues to attract strong developer interest, with DeFi projects and institutional pilots adding credibility. TVL remains among the highest in the industry outside Ethereum, and partnerships with traditional companies reinforce its mainstream positioning. Priced near $22, analysts forecast AVAX could revisit highs of $40, offering some upside for long-term holders.

While both SUI and AVAX represent strong Layer-1 plays, analysts stress that neither is likely to deliver the kind of parabolic multiples retail investors crave. That space belongs to cultural tokens with the ability to capture attention and scale virally.
A balanced strategy
For investors, the question isn’t simply SUI or AVAX. Both bring unique strengths: SUI with its speed and developer-friendly design, AVAX with its subnets and enterprise appeal. Each could deliver solid multiples in a healthy market. But for those seeking to balance credibility with exponential upside, pairing them with a cultural play may be the optimal strategy.

Conclusion
SUI and AVAX are proving themselves as leading Layer-1 contenders heading into 2025. They are fast, scalable, and increasingly attractive to developers and institutions. But while their upside potential is strong, it may not match the parabolic rallies that define crypto headlines. For investors asking which is the better bet, the answer may be that SUI and AVAX provide stability, while other tokens may provide higher-risk, high-reward characteristics. Together, they form a strategy that balances today’s proven platforms with tomorrow’s breakout contenders.
