Comparison
It depends on your priorities and experience level. Both telescopes score identically at 73/100 overall, but they serve different observing needs. The single most important differentiator is aperture versus portability; the Celestron PowerSeeker 127EQ offers 13mm more aperture for superior light gathering and planetary detail, while the National Geographic Explorer 114mm weighs 60% less and features a faster f/4.40 focal ratio better suited for wide-field viewing and astrophotography.
The Celestron edges ahead for deep-sky observation and planetary work, scoring 41 and 48 respectively compared to the National Geographic's 45 and 42. However, the National Geographic's lightweight design and alt-azimuth mount make it more accessible for beginners hesitant about equatorial mechanics, plus its superior portability score means you'll actually take it outside more often. Buy the Celestron PowerSeeker 127EQ if you plan backyard observing sessions from a fixed location and want the best planetary views.
Buy the National Geographic Explorer 114mm if you value portability, casual stargazing, and a gentler learning curve. For most beginners, the National Geographic's ease of use and lower price slightly edge out the Celestron's optical advantages, but serious planetary observers should invest in the extra aperture.
