The superconducting properties of several HTS coated conductors (CC), which had different tape structures, fabricated by KERI, X and Y institutes were compared. We have fabricated the $high-J_c$ SmBCO CC, which has 273.5 A/cm, $1.2MA/cm^2$ and 93.5 K for $I_C,;J_C;and;T_{c-zero}$, respectively, using the EDDC (Evaporation using Drum in Dual Chambers) process. Both X and Y institutes CCs, however, were purchased. The n-values of KERI, X and Y institutes CCs are 58.5, 40.7 and 31.5 in $V=1{sim}10{mu}V$ criterion, respectively. The in-field properties of $I_C$ at 77K were investigated and the $J_C(B)/J_C(0G)$ at 0.5 T with $B{perp}$ ab-plane are 0.31, 0.19 and 0.24 for KERI, X and Y institutes CCs, respectively. From the $I_C-{ heta}-B$ measurement, we observed that the ab-plane of ReBCO phase was tilted for the ab-plane of substrate in the KERI and X institutes CCs. The tilted angle is about 5 degree. We confirmed that the peak shift (as an inclined texture) was observed by X-ray (102) pole figures of the SmBCO for the KERI CC.
