Investors choosing between the ARK Space & Defense Innovation ETF (NYSEMKT:ARKX) and U.S. Global Jets ETF (NYSEMKT:JETS) must weigh a more expensive industrials-heavy basket against a pure-play airline focus.

Which looks like the better buy

The ARK Space & Defense Innovation ETF (ARKX) and the U.S. Global Jets ETF (JETS) are very different funds. Their common link is a flight-based theme, with the former pointed toward the final frontier and the latter about terrestrial-bound movement in the skies. Choosing which to invest in depends on the factors that matter most to you.

ARKX is focused on disruptive innovation in space exploration and defense technologies. This holds the potential to deliver superior returns compared to JETS, as demonstrated by its greater total return over four years. Its expense ratio is higher because it's an actively-managed fund, so that's less of a drawback than the fact that its holdings contain speculative bets.

JETS is more for conservative investors, given its holdings target tried-and-true airline companies. Its dividend and lower expense ratio make it the more appealing ETF for those who want to hold for the long term. It also has a longer history for investors to gauge performance across various macroeconomic conditions.
