EUV

The Corgi Lithography & Semiconductor Photonics ETF takes a wider angle on photonics, centered on lithography and chipmaking: the light-based tools that print chips, the equipment makers around them and the foundries that use them. Large positions have included ASML, TSMC, Applied Materials, Lam Research and KLA. Because it leans on large semiconductor equipment and foundry names, EUV behaves more like a chip-equipment fund than a pure optical networking fund. That can make it steadier than the pure plays, but it is a different bet.

EUVX

The Corgi Lithography & Semiconductor Photonics 2x Daily ETF aims for twice the daily move of its lithography and semiconductor photonics strategy. Leveraged ETFs reset every day. Over periods longer than a day, returns can differ a lot from 2x the underlying move, especially in choppy markets. These are trading tools, not long-term holdings for most investors.

Lower fees and more assets are helpful, but they are not the whole story. The bigger question is which strategy matches what you want to own. This comparison is not a recommendation to buy or sell either fund.
