This isn't really about which tree is better. It's about where you live. Got a sunny windowsill and no outdoor space? Ficus. Got a balcony, patio, or yard? Juniper. That's it. That's the decision.
Keep a juniper indoors and it'll slowly yellow and die over 3-6 months. Stick a ficus outside in a zone 6 winter and it's dead by morning. These trees need opposite environments. Your setup picks for you.

Environment is the only filter that matters first. Junipers need outdoor life: full sun, wind, rain, seasonal temperature swings, winter dormancy. They literally cannot survive indoors — not even near a bright window with a grow light. Ficus needs warmth: keep it above 60°F, with no frost and no cold drafts. The overlap between their happy zones is nearly zero.
Watering shows different failure modes. Ficus stores moisture in its thick leaves and bounces back from a missed watering. Juniper is sneaky — drought damage doesn't show for weeks. By the time needles start browning, the interior foliage is already dead. Check juniper soil daily in summer. Stick your finger in. If the top half-inch is dry, water.
Aesthetic languages are completely different. Juniper: layered foliage pads, bleached deadwood, windswept forms, dramatic wiring. Mountain tree energy. Ficus: smooth bark, aerial roots, spreading tropical canopy. Banyan energy. They produce such different results that most growers eventually want both.
Pruning tolerance gives ficus the edge for beginners. Cut a ficus branch too short and it back-buds from old wood — mistake recovered. Cut a juniper branch past the green growth and it's permanently gone. Dead stub. No second chances. This makes juniper pruning more stressful for new growers.
Growth calendar differs. Ficus pushes growth year-round in warm indoor conditions — feed it monthly and it never stops. Juniper has a defined spring-through-fall growing season, then shuts down for winter dormancy. Different rhythms, different maintenance schedules.
No outdoor space? Ficus. Period. Don't try to make a juniper work indoors. It won't work. Every "my juniper is dying" post online traces back to someone keeping it inside.
Got outdoor space? Juniper delivers more dramatic bonsai more quickly. Better wiring response, deadwood potential, and that classic silhouette everyone pictures when they hear "bonsai." It needs daily attention in summer, but the development speed outdoors is worth it.
